Hello,
Is OPCache known to cause registration issues in Event Espresso? We are on a VPS with Liquid Web.
I received this message today and trying to figure out the problem:
“An error has occurred: Your form data could not be applied to any valid registrations
EE_SPCO_Reg_Step_Attendee_Information –
process_reg_step – 750”
Thank you.

May I ask is OpCache the only type of caching you’re using? Also, do you have any plugins installed like NextGen Gallery?

OPCache is the only type of caching being used. We do have other plugins, but not NextGen Gallery.

OpCache has the potential to cause problems if it’s not getting flushed after updating plugins or WordPress core.
Here’s a guide that explains a bit more:
https://www.sitepoint.com/understanding-opcache/
This would be an important configuration step when using opcache with WP:
First of all, probably in each typical project you will have to ensure that the opcache.use_cwd option is set to true. Enabling this setting means that the OpCache engine will look at the full file paths to distinguish between files with the same names. Setting it to false will lead to collisions between files with the same base name.
So if you want to use OPCache you’ll need to make sure things are configured properly and that you can test/debug on a staging server first.
