Completed form sometimes does not direct to Paypal

Sometimes, but not always, redirection to Paypal does not occur for users. I have not been able to replicate it, since it’s intermittent. I read the documentation at https://wpplugin.org/documentation/contact-form-7-form-does-not-submit/ as recommended in other forum posts.

I have the latest version of the plugin, 2.2

Php is v8.2.17

There are two “must-use” plugins for caching, installed by the hosting company, Endurance Browser Cache and Endurance Page Cache.

I don’t see any page-level settings for caching.

I’m not using any of the javascript plugins the article mentions.

The only plugins specifically tied to CF7, other than yours are ReCaptcha v2 for Contact Form 7 1.4.5 and Redirection for Contact Form 7 3.1.2. The latter is not the same as was listed as a possible conflict in the documentation, but I wonder now if I don’t need it anymore? Does your plugin handle the redirection?

It’s hard to test any changes I make to see if they work, since I haven’t been able to replicate the issue.

Is there any possibility the user’s own browser settings could be an issue?

Thanks!
