Show Updates For All Sites results in blank page

the same problem here, please advise

What messages, if any, are logged in your browser’s console? (See: https://updraftplus.com/faqs/how-do-i-open-my-browsers-developer-tools/ )

Thanks for the answer, please take a look at the console

Thank you. Please can you post a screenshot of what you get if you click the arrow on the line “Uncaught -> d” to expand the information there?

Also – does the same happen if you temporarily de-activate all other plugins and switch to a default theme (e.g. TwentyNineteen)?

I can’t reproduce the error on a blank WP install that has nothing except UpdraftCentral. So we will need your help to get more insight into the conditions that are causing it.

Sure, here it is “Uncaught -> d”

When I press show updates, this error appears

The same happens also with all deactivated plugins, I left only yours. It has something to do with WP newest update since prior that, everything worked well.

Thank you. It is to do with cacheing of resources from a previous UC version. What happens if you hold down Control and reload from your browser – does that fix it? If you are aware of other caches (e.g. at the web-hosting level), please flush those also too.

Thanks, brilliant, looks like holding ctrl and pressing reload of that page solved the problem. Now everything loads well.

Thanks again.
