ISPConfig 3.1 and Joomla 3.7.2 with PHP 7.1

Hi,
For one of the sites using Joomla in ISPConfig I changed PHP from default PHP to PHP 7.1
Here are the settings:

PHP: Fast-CGI
PHP Version 7.1.0
Apache/2.4.10 (Debian)
WebServer to PHP Interface cgi-fcgi
Joomla! Version Joomla! 3.7.2 Stable [ Amani ] 22-May-2017 09:46 GMT

I get this error:
Error displaying the error page: The memcache Cache Storage is not supported on this platform.: The memcache Cache Storage is not supported on this platform.

Only answers I found was to make /administrator/cache folder writable - did not work. Do you think this is related to joomla, php or ispconfig?

 

Have you check this out?

 

Thanks for your reply ahrasis!

I did check that link before I posted.
All joomla folders are writable except file configuration.php which shouldn't be.

I ran: chown -R web8:client8 /var/www/clients/client8/web8/web/
still same error

Any other ideas, anyone?

 

Yes, I confirm what Till says:
1. Either memcache is not installed on this version of PHP. You can check that in the joomla admin > System info, in the php info tab. Look if you can find memcache in the list of PHP modules. If not, you may be able to install it.
2. Use the filesystem to handle the cache instead of memcache.

 

Thanks that makes sense. Memcache is not installed with PHP 7.1
How would I disable memcache for this one joomla site? Is doable in Apache Directives?

 

I guess you don't have access to the back-end of this site because of memcache problem? If so you can fix this by editing, via FTP, the configuration.php file of this site.
You should have a line with

public $cache_handler= 'memcache';​

and set it to

public $cache_handler = 'file';​

You may need to set the permissions on this file to 644 before editing it.

 

Thanks Jean-Francois
I already had tried public $cache_handler = 'file';
before my post #6,
didn't really work.

I tried again and it works now, thank you so much!

 

Glad I could help.
