CMS Made Simple Forums

Hello, I have upgrade from php 5.6 to php 7.0 and get some error 500 when I try to use the module manager. I can enter and see the modules but not upgrade or install new. Each time it brings me to the following error:
--------------------------
Server error!

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.

If you think this is a server error, please contact the webmaster.

Looking at the cpanel from Infomaniak, I can see the following line:
$_SERVER['ORIG_SCRIPT_FILENAME'] /home/clients/c389a9272f447bd57005e45aeff9eb7a/.config/apache/WEBSITE/.fpm/php5.external
Is there something there that I should manually modify? If so, how?

Thanks!

I would try the following, test after each one:

1. make sure you're using the latest version of cmsms
2. confirm mod_security isn't enabled
3. clear the cmsms cache
4. check the system info to make sure you have all green checks, and resolve as necessary
5. check .htaccess and php.ini for anything unusual (or temporarily remove them)

If you still can't get it to work, you'll need to examine the error logs and try to provide information to your host about possible missing extensions or something.
