Contact Form 7 error

Same problem with contact form 7 and woocommerce filter.

@matoni555, does this issue stop occurring if Cache Enabler is deactivated? If yes, would it be possible to receive your Site Health Info? This can be obtained by going to your WordPress dashboard > Tools > Site Health > Info > Copy site info to clipboard. A screenshot of your Cache Enabler settings would also be helpful.

Yes, it ok after if Cache enabler is disabled.

This is a problem in Contact Form 7, roll back the version and everything will work. I’ve got 200+ sites out of order .. there is a problem in version 5.4 .. and the problem with all caching plugins is not only this.

@siteussia, has this issue resolved with the release of version 5.4.1 for Contact Form 7? When checking the changelog of this plugin it looks like this issue may have been addressed, however, a confirmation from you and/or @matoni555 would be great.

@coreyk Yes, it seems ok now. Thank you

Thanks for the confirmation, @matoni555. It’s sincerely appreciated!
