Hello, I have used EE in the past on other sites. I have an active key and I created the events in a pretty typical way. So far these are free events.
Here’s an example.
I am getting an error each time – This registration step cannot be completed. Please refresh the page and try again.
I’ve deleted the cache at the server for the website also.

Hi there,

There’s a fatal error being thrown on the ajax request in the background which is preventing registrations.

We’ll need the full error to know what is happening here, your host will usually have a section you can use to view errors being thrown on your site within your control panel, if you check there can you see any from Event Espresso.

Or if you have FTP access it usually an error_log file in the root directory of the site.

If you can post that error we can investigate this further.

Hey, that seems reasonable but the only error I have in the log is from Friday when we launched the site: [Fri Aug 14 16:18:24.911469 2020] [authz_core:error] [pid 24421:tid 47060988507904] [client] AH01630: client denied by server configuration: /home/osuhillel/public_html/wp-content/cache/autoptimize/index.php, referer:

I can send a screenshot so you can see this is the most recent and there aren’t others, but I’m not sure how to attach here.

Oops wait I went to the file manager like you suggested and found the EE errors.

The first one is actually an access log but it does highlight that you are using autoptimize, which can cause issues, more on this late as first we need to fix the fatal.

I’ve removed the majority of your post as it’s all the same error (above).

That error means there are files missing from your install of Event Espresso, or EE can’t access the files within itself (which would be weird), so the first step is to reinstall Event Espresso.

First, download Event Espresso from your account page, save it to somewhere accessible on your machine, desktop for example. (Note if your on a MAC it will likely automatically extract it again, just re-zip the event-espresso-core-reg directory again if that happens).

Now, de-activate and delete Event Espresso in in dashboard -> Plugins.
(None of your Event/Registration/etc data will be removed, thats all in the database and we don’t delete it when you remove EE).

Once that has been removed, go to Dashboard -> Plugins -> Add new -> Upload plugin.

Select the .zip file you just downloaded/recreated on your machine, install and activate again.

Let me know when that’s complete and I’ll retest.

May I ask, did you previously install using the plugin manager (Dashboard -> Plugins -> Add new -> Upload plugin) or using FTP? (I ask because FTP installs can fail and randomly skip files during transfer)
