jQuery Ajax Error 0 on Save and Drag Order

Fri, 07 Jun 2013 11:15:50 -0700

Thanks Dave! This workaround fixes my "error 0" popup issue on empty jQuery/AJAX calls! Made my day!

At this point, the issue seems to only effect cmsAdmin directory. Upon testing, I only receive a "0" response within the CMSB Admin directory on shared servers with Apache 2 and running PHP as CGI. I sent Dave an email with more troubleshooting info; so maybe he'll discover (and hopefully explain) what's happening. Ultimately, I could have a unique issue. We'll see...

jQuery Ajax Error 0 on Save and Drag Order

Wed, 05 Jun 2013 15:16:46 -0700

The issue started around May 17th to previously installed (and working) CMSB's on multiple servers. I'm having our web host look into this first so I don't waste your time if the issue is on their end (wouldn't be the first time).

HOWEVER, I did discover something interesting... If I remove the php.ini file located within the cmsAdmin directory, I receive a 500 error ONLY when trying to access menu items under the "Admin" tab (General Settings, Section Editors, Code Generator, etc.). All the other content editor menu items/links load correctly and content can be modified/saved as usual. I replaced the php.ini file and the Admin menu items started loaded again. Almost seems like paths are modified if any .ini file exists within the cmsAdmin directory.

Does this connect the dots for anyone?

jQuery Ajax Error 0 on Save and Drag Order

Tue, 04 Jun 2013 17:15:38 -0700

Applies to CMS Builder v2.15 - v2.53 and Firefox v20 - v21

"error 0" POPUP MESSAGE in CMSB admin (only on following jQuery/Ajax calls):
- Admin > Section Editor > MySection > Field Editor 'Save' button (error 0 popup... saves field options, but must select 'ok' then hit 'Cancel' to exit Field Editor)
- Admin > Section Editor > MySection "drag / sort field order" (error 0 popup... saves field order, but must select 'ok')
- Admin > MyMultiSection "drag / sort record order" (error 0 popup... saves record order, but must select 'ok')

STRANGE, BUT NO "error 0" POPUP MESSAGES FOR: - Admin > Section Editor "drag / sort section menu order"

SERVER INFO:
Shared Hosting
Linux System running Apache 2
Server API: CGI/FastCGI
MySQL Versions Tested: MySQL v5.0.51a and MySQL v5.0.91
PHP Versions Tested: PHP v5.2.17 and PHP v5.3.13

ADDITIONAL TROUBLESHOOTING INFO:
I suspected the error started from either a server config update via host or browser bug/depreciated cross-site support. I tested the root html directory AND the CMSB Admin directory (on multiple web servers) using the "php_exit_bug.php" test script that Dave provided in another post. I only receive a "0" response within the CMSB Admin directory. The root directory and all other sub-directories exit with NO response (correctly). So... This leads me to believe a CMSB directory setting is causing the conflict. Any settings within the default CMSB .htaccess or .ini that would cause this?

That's a good point equinox69, but unfortunately, it was one of the first things I tried. File dimensions, color-space, unknown extensions, and file corruption can always have the potential for generating upload errors. I tested a handful of different files/file-types; all which produced the same error.

Thanks for test file Dave. I put it in the CMSB directory and tested it with a 5MB file and a 14MB file. The 5MB file displayed successful upload results. The 14MB file displayed a 500 Error page.

I called the web host tech support and they mentioned PHP had a 32MB limit (which is BS). The tech support guy put me on hold... 5 min later he said I now have a 32MB limit. HOWEVER... before I hung up the phone, I refreshed my phpinfo test page and it served me an ERROR PAGE! In fact, all php pages within the CMSB directory served up the same ERROR. He stuttered for awhile after I informed him of the directory error, then he said... a ticket was created and sent up a few tiers. [crazy]

Well... I looked into the new issue and it appears the Default PHP Version was changed to v5.3 by Tech Support. I set the Default PHP Version back to 5.2 and my php pages started loading again. v5.3 could have conflicted with directive php.ini values in CMSB directory. Anyway... I'm still waiting to hear back from a more knowledgeable hosting tech support rep. I'll let you know what I discover.

Re: [Dave] Error uploading 10MB+ files server returned: HTTP 500

For the actual upload field config, I tried both unlimited (box unchecked) and a value of 51200.
Within Admin > General Settings the last line displays the following...
Server Resource Limits: CPU Time: 120 seconds, Memory Limit: 200 MB, Processes: 64306

Is there any chance CMSB is calling PHP Version 5.3 during the upload process instead of my Default PHP Version 5.2? Other than that, the only possible explanation could be Apache settings trumping PHP.INI during execution. Could this happen even when PHPINFO displays my revised/desired values?

Error uploading 10MB+ files server returned: HTTP 500

Wed, 14 Nov 2012 18:20:43 -0800

Has anyone ever received HTTP 500 errors when trying to upload larger files (10-12MB and up) using CMSB admin file upload field (both flash and non-flash) with the following configuration and troubleshooting? . . .

ERROR DISPLAYED in CMSB admin AFTER UPLOAD REACHES 100% (only when trying to upload files 10-12MB or larger):
"Error uploading 'my-14mb-test-file.pdf', server returned: HTTP 500"

SERVER INFO:
Shared Hosting
Linux System running Apache
Default PHP Version 5.2.17

DEFAULT PHP.INI REVISIONS (also added these to php.ini for CMSB directory and custom upload directory):
upload_max_filesize = 100M
post_max_size = 200M
memory_limit = 120M
max_execution_time = 600
max_input_time = 900
;; note... Using default value for upload_tmp_dir

ADDITIONAL NOTES:
CMS Builder v2.15
PHPINFO test displays revised (correct) .ini values
Upload field configured to accept multiple file extensions (including PDF) and unlimited file size
Error when configuring upload field with both custom upload directory and default
CGI Error log shows nothing

[mad] Am I missing something? Should I direct my attention to Apache settings OR to settings within CMSB?

OK. . . Thanks for clearing that up. Sounds like I'll have to create a custom workaround. Just didn't want to "re-invent the wheel" if CMSB Admin area already had a simple way to import/input large global data lists.

Thanks Chris!

Hi Chris.

There are actually a couple reasons. . .

1. Don't really want to create 100 records and then cut/paste 100 times for each drop-down list item [crazy]. Unless I can batch records from text file array or CSV??
2. Would like to create some kind of template for "global" values. (ex: "Available Colors" list options for product A, B, and C would be different from products D, E, and F)

Lets say you have Possible Color Names based on each manufacturer. And you have a section to create records for products by each manufacturer. AND the Color Names change every year.

Is there any way to swap out last year's Color Names list with this year's Color Names list with a single copy/paste?

Thanks!

How to Create a Global Dropdown List (list options)

Wed, 14 Oct 2009 14:04:13 -0700

Seems simple, but I think I'm looking at it the wrong way. . .

Trying to narrow down the reasons for my admin drop-down list issues. Maybe someone could clearly explain how to accomplish the following:

CMSB v1.33
For Admin (add/edit) area use only:
1. Create one "global" or "master" list of drop-down options (like 100 options)
2. Use/Load the above data for list options when creating the corresponding List Field within Section Editors.
3. When the "master" list changes, all drop-down list options of that field will update.

I tried many different approaches, but could only produce
