When sending the form for the first time I often get an error message

Hi @karlmeral,

This issue replicate because of your site caching issue. If your cache plugin provides the exclude cache from your specific pages. Please check this documentation https://docs.wpeverest.com/everest-forms/docs/how-to-configure-caching-plugins and follow the instruction.

The form does not have any issue when user visits your site for the first time. You can see in this screenshot https://i.imgur.com/GMTzFGt.jpg.

Hello. I am seeing the same issue and might be related to what you are referring to. I am using ‘Autoptimize’.

I’ve added- /contact-form to the excluded. Am I missing anything?

Disabling Autoptimize seems to fix the issue, but I do like using this plugin….I’m not sure how popular this specific plugin is, but if you happen to get guidance on what to Exclude and where I would implement.

Thanks for looking.

Hi @elevenhagen,

We have guided a few popular plugins, and our documentation shows how you exclude the caches from the form page. The solution is simple. You need to exclude caching the form page.

If the Autoptimize plugin does not have such a feature to exclude caches, we recommend you contact the respective plugin author or try a different caching solution for your site.

Regards!

Autoptimize does not do page caching, so as such one cannot exclude a page from being cached by AO. What might be needed though, is exclude specific JS (or CSS) from being optimized by AO, in which case one has to add an exclusion, most often (part) of the URL of the JS/ CSS.

In this case the exclusion could be wp-content/plugins/everest-forms/ I think? ??

Hi @optimizingmatters,

For each submission, the Everest Forms requires a Nonce key. This security key is randomly generated and unique for each form submission. Using a caching system might not let the Nonce key be generated again, using the same old key for another form submission as well. Therefore, the submission will be interrupted.?So we suggested removing the page that has the Everest Forms from the caching system. Doing this won’t hamper the actual cause of caching used in your site and will also increase the form security.

Excluding CSS/JS from caching is not possible to fix this issue because it is also related to security. ??

Regards!

I had the same problem, but only when forms were submitted from mobile devices. I was able to fix the problem by using both solutions from elevenhagen and Optimizing Matters. I also deselected minify excluded css ad js files from Misc Options.I’m not sure if all of these steps are required, but it doesn’t seem to be hurting anything and my form submissions now appear to be working on the first try.
