It looks like you’re running short on memory according to the messages. Have you tried to clear out your cache manually by deleting var/cache? Here’s the docs for working with memory limitations: [Working with php.ini resource limits | Mautic Community Documentation](https://docs.mautic.org/en/troubleshooting/working-with-php-ini-resource-limits) ---

Is this from the PHP file that Mautic reports to be using in your system settings phpinfo file, remembering that sometimes a server may have a different file for each version of PHP and for the command line (caught me out before!)? Do the errors continue after you have deleted the var/cache folder? Also have you tried to check the post max size and increase that also? Can you access it in an incognito browser (may indicate a cookie issue if so)? ---

Hi, thanks for your reply. Following my upgrade to Mautic 3.2.5 I found that there was an issue with the MySQL database connection. I uninstalled/deleted the 3.2.5 version of Mautic that was updated from within Mautic. I used FTP to install Mautic 3.2.5. Install was successful with full access to login page and dashboard. From within Cpanel I have tried to restore my backed up data base to the 3.2.5 version of Mautic but recevie the following error: Error: The system failed to execute the database script with the following errors: ERROR 1215 (HY000) at line 25: Cannot add foreign key constraint My Mautic 2.16.3 Database Backup was created by MySQL version 5.6. My current server details Server: VPS PHP Version: 7.3.27 MySQL Version: 5.7.33 Operating System: linux Are there any known issues with this? I appreciate your feedback and suggestions on how to restore my database to Mautic 3.2.5. Thank you.
