Warning: array_key_exists() expects parameter 2 to be array

Hi SI Team

Following the docs here:

https://stackideas.com/docs/payplans/administrators/welcome/minimum-system-requirement

Recommended Requirements

To get the best out of PayPlans, below are the list of recommended requirements for your site.

Joomla 3.8 and above is installed.
PHP 5.4 and above is installed.
PHP Extensions: Curl Library. (It is required by PayPlans to perform outgoing connections)
PHP Extensions: ZIP Library. (It is required by PayPlans for faster extraction process)
PHP: [upload_max_filesize = 32MB].
PHP: [post_max_size = 32MB].
PHP: [magic_quotes_gpc = Off].
PHP: [memory_limit = 64MB];
PHP: [max_execution_time = 30];
MySQL v5.2 and above.

I asked Site Ground to set magic quotes as suggested above which resulted in a White page with the following error:

Warning: array_key_exists() expects parameter 2 to be array, null given in /home/finalb9/public_html/libraries/cms.php on line 62

Warning: session_name(): Cannot change session name when headers already sent in /home/finalb9/public_html/libraries/joomla/session/handler/native.php on line 128

Warning: session_cache_limiter(): Cannot change cache limiter when headers already sent in /home/finalb9/public_html/libraries/joomla/session/handler/native.php on line 235
Error: Failed to start application: Failed to start the session because headers have already been sent by "/home/finalb9/public_html/libraries/cms.php" at line 62.

Site ground have since set magic quotes back to the way it was = does not strictly speaking adhere to above requirments.

They are trying to get a way to set the magic quotes correctly with out the site crashing.

Just thought that I would let you guys know.

Will update when I know more from Site Ground

thanks
