Manually Uninstalling Event Expresso 4

Can someone PLEASE give me a step-by-step how to MANUALLY uninstall this software? The Maintenance function DOES NOT WORK, so please let’s just not go there. It’s a long story but my WordPress site did not have table prefixes and this software produces a lot of errors because of it. I then added table prefixes and the Event Expresso Crashed (white screen of death).

I can see the tables I need to drop but there are a bunch of entries in the WordPress tables (options and postmeta tables) that I cannot figure out how to remove. I want to reinstall this software from the beginning so it is imperative that I remove all artifacts of this software first.

Time is of the essence so if anyone can help me I would greatly appreciate it. I do not want to try any other workaround, I just want to remove all traces that this install left behind. It is just the core install to remove, no add-ons.

Here is the error I get when I try to install:

Hi there,

May I ask what on the maintenance section you mentioned doesn’t work?

The quickest/simplest method to doing this is to get EE to activate and then use the maintenance mode section you mentioned earlier to drop all the EE4 data. The steps I would take are:

1. Backup the DB.
2. Drop all the EE4 tables (esp_* tables)
3. Activate EE4, you may get a notice stating the tables don’t exist and EE recreated them.
4. Go to Event Espresso -> Maintenance -> Reset/Delete Date -> Permanently Delete All Event Espresso Data.

That will remove all of EE’s CPTs from _posts table then all EE tables and date (options), remove any cron tasks added and deactivate EE.

Now, I know you said you don’t want to try any other workaround but the above is your best option here. If you do still want to do this all manually, you’ll do steps 1 and 2 but then need your own script to remove the EE4 options. You can take a look at in:


It should be around line 1553 and that loops over the EE options and removes them, you’ll need your own script that does the same based on that, or you can manually remove each option listed in that method if preferred.

As I said the Maintenance option will not work otherwise this would have been done 5 days ago. I get a white screen of death, meaning NOTHING show up anywhere. I have a huge mess!

So you’re still getting a fatal error on the Maintenance page even after you’ve dropped the EE4 tables from the DB?

If your getting a White Screen Of Death then a fatal error is being thrown and will be logged in the error logs. Is it the same error you posted above or another?
