I installed EE4 with an old version of EE3 and when it went to migrate the database the migration hung (1 hour with no response). I could then not get into my WP admin panel, I would get an internal server error. I had to go into the site file manager and delete the plugin to be able to access my WP site. I deleted all EE plugins and all EE tables from the database and re-installed, as soon as I activate EE i get the internal server error and cannot access WP.

Hi Greg,
It may help to run the Event Espresso requirements check plugin to see if your server has the minimum requirements to run Event Espresso 4. You can download a copy here:

My server is running PHP 5.3, MySQL version 5.5.32 and WordPress 3.9.1 I ran the requirments plugin and it passed with warnings, saying it may have difficulties with all features.

Hi there Greg,
Are you seeing any errors in your site error log?
This is usually available in the WordPress root and can also be available through a hosting panel or a cpanel login.

Hi Greg,
The key part of the error message is this:
PHP Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 19456 bytes)
Which means the server is running low on memory, and completely runs out when you try to activate Event Espresso. You can try increasing the amount of memory available for WordPress by following this guide:

Hi Matthew,
Your error message is saying that you already have another version of Event Espresso active. You’ll need to deactivate the older version of Event Espresso before activating Event Espresso 4. You can manually deactivate the older version of Event Espresso 3 by following any one of these guides:
