When I choose more dan one ticket per event I get following error:
“An invalid response was returned from the server while attempting to process your request. Please refresh the page and try again or contact support.” https://bbqacademy.be/data-en-inschrijvingen/
I did add a plugin/snippet ( This snippet reduces the value set on a promotion code if is it as ‘dollar discount’) but disabling that has the same result.
We’ve been investigating this and found a possible cause with one of the PHP8 fixes we included in the last update (the issue doesn’t happen for everyone, it depends on your setup).
I’ve just pushed the latest version of Event Espresso live, which is version 4.10.35.p, can you update to that version and see if that fixes the above on your site?
If you don’t see the update live yet go to Event Espresso -> General Settings, just hit save to force an update check and the update should then show in Dashboard -> Plugins.
The support post ‘invalid response’ is closed to new replies.
