“Problem with nonce. Please delete cached page from settings page.”

Hi @jsmo

What version of WP Super Cache are you using?

Hi @jsmo,

I have tested WP Super Cache alongside Autoptimize on my test site, and can’t see any issue with running these plugins together.

The error message “Problem with nonce” is interesting. It can mean a few different things, depending on a number of circumstances. The most likely explanation is that you were viewing a very old cached version of your homepage.

This might happen if you have “Enable caching for all visitors” selected in the WP Super Cache “Advanced” settings, and a very high number under “Cache Timeout” on the same page. Can you please check both of these settings?

Generally, I’d recommend only enabling caching for users who are not logged in.

But the weird part is that you report still seeing that error message after deleting your cache via the wp-admin area. Do you have any other caching tools enabled, which may be caching your homepage?

Can you please try an experiment, to see if it gets past the issue? It’s quick an easy:

1. Visit your homepage, but add “?cache_buster=” followed by a random number to the web address. e.g.: “http://example.com/?cache_buster=12234”
2. Try clicking on the Delete Cache option in the admin bar.

That first step should bypass any caching that may be loading a stale nonce. If that works, try visiting your homepage normally, and checking if the “Delete Cache” button still gives an error.
