Sorry for the delay.  The 403 indicates the issue is probably coming from somewhere else outside of Permalinks & CMSB.  I'd check your .htaccess files and server logs to see what the cause might be.

Let me know any questions.

I get a 403 after removing the /catering permalink and trying to access it in the browser.

That is curious.  What happens when you temporarily remove the /catering permalink and access /catering in the browser?  Do you get a 404 or a 403? 

/rewards

/contact

etc.

I made them manually but also have a section with a permalinks text field and a locations details viewer all working. 

So the plugin is installed and htaccess works.

However, /catering does not work. I get a 403

The plugin entries all look consistent.

Going to /catering.php works fine.

I renamed rewards.php that works with /rewards to catering.php and that won't work with /catering either so any page for /catering doesnt work.

I looked into the actual database in cpanel and it appears consistent with one /catering entry. 

I updated to cmsb  v3.71and permalinks 1.12, no luck.

I deleted the /catering entry in the plugin and re-added. Doesn't work.

Any ideas?
