I received the below from domain.com
"The PHP version of the account is set to the current latest PHP 7.4 version. Additionally, I checked the recent error logs of the account at
www1.domain.com/controlpanel/cgiManagement/cgierrorlog.html and found recent errors are related to PHP memory limit.
I checked the PHP memory limit of the account in the php.ini file of the account at
www1.domain.com/controlpanel/cgiManagement/phpplus.html and it is currently set to the maximum possible limit on our shared hosting platform, that is 512MB. I’m afraid if this was causing the blank pages on the website. Rest assured, all the pages are working at the moment. It is advisable to test the pages for few days to make sure there are no issues on the website again.
If the issue still persists, it is advisable to contact the website application vendor Joomla to check if there are any issues from their end. Additionally, if they ask to update any settings from our server end to fix the issue, it is advisable to reply back to this email with relevant information. We will be glad to help you."
