I got two zip files from a client, one the website, the other the mysql db.

I installed the files on my server, changed some settings in /admin/data/settings.dat.php and some of it seems to be working :)

I found out the people (who originally created the site for my client), who I can't ask for help (long story), used a version of CMSB.

I don't know how old (some of) it is, but I guess old as I got some error solutions saying that kind of php has been obsolete since 5.4

I can enter the admin part, and edit quite a lot. Although the "start" page of the admin section is, apart from the side bar, blank (but keeps growing after opening).

The homepage of the site still does this:

https://www.ceciledumoulin.es/

(It's a mess)

Now I'm a bit stuck and would really appreciate some help, some pointers as how to tackle the problems one by one.

Yesterday I did try to look if it was possible to enable php 5.4 on my server (which is not a good idea, I know), but anyway, that's simply impossible so I'll have to work on the site itself to get it working.

Thanks for any ideas!

(If you'd like more information, I'm happy to share whatever I can of course.)
