Website breaks when EE is activated

One of the EE updates broke my site a while ago. It did not even activate the wordpress plugin misfunction protector (and I had to change the plug-in name to make the site work). I thought that future updates would fix this, but it still breaks when activated.

What is the next first step? Should I reinstall the plugin? Should I delete it first, then install it?

Here is the error that pops up:

The class file EE_Caf_Messages could not be located or is not readable due to file permissions. Please ensure that the following filepath(s) are correct:
/home/*****/public_html/wp-content/plugins/event-espresso-core-reg/caffeinated/ EE_Registry - _require_file - 1157

/* */

Thanks for any help!!

Hi there,

The error you are getting indicates that either there are files missing from your EE install, or your server’s permissions don’t allow your site to access them (the latter would be strange if the above is the only file throwing that error).

How are you updating the plugin? Through the dashboard or FTP?

Do you have plenty of space left with your hosting provider? (We see issues like this if you are currently almost at your allocated storage allowance and then the update tasks you over and the files are ignored. Note I’m not saying that is the issue here, but worth a check)

Which version number of Event Espresso are you currently running?

Hi Tony. It is 4.10.43.p. We also have Attendee Mover (EE4.9.13+) [Version 1.0.7.p] and WP Users (EE4.6+) [Version 2.0.19.p] if that matters. It was likely updated via dashboard. Should I reinstall it? If so, should I delete it first (I’m worried about losing the data). And should I go through FTP or dashboard to do so? Thanks!!

(I’m worried about losing the data)

Ok, stop.

First thing to do right now, is to create a database backup.

All of you EE data is stored within your site’s database so you want to keep regular backups of the full database. If you host doesn’t provide a backup solution then there are multiple plugins available for backups:

Use whichever one you prefer just create a full database backup.

None of your event data is stored within EE’s files so replacing the plugin doesn’t lose data.

I don’t recommend updating via FTP, its too easy for files to drop and most people don’t delete the plugin prior to updating via FTP which then cause fatal errors.

Download the .zip file for 4.10.46 from your account page.

Then on the site itself go to Dashboard -> Plugins -> Add new -> Upload plugin.

Select the .zip you just installed.

You already have EE installed so WordPress should ask if you want to replace the current version with the one you just downloaded, click to do so.

You should now be on the latest version.
