Thanks for the tip. Switching back to default theme does work in terms of regenerating all images.
All problems solved. I can see the webp images created in the uploads-webbpc folder as well.

1. Do you have any error on the plugin settings page?
No Error

7. Content of your .htaccess files from directories /wp-content/uploads and /wp-content/uploads-webpc (pasting the code using the CODE shortcode in the editor).
*/wp-content/uploads*

text/x-generic .htaccess ( ASCII text )

8. What plugin version are you using? If it is not the latest then update and check everything again.
1.2.5

9. Used WordPress version.
5.4.1

10. A list of all the plugins you use. Have you tried checking the plugin operation by turning off all others? If not, please try whenever possible.
the list is too long to test.

Indeed I have. How else would I have checked server config and run developer tools to get http error and error message?

But your reply sounds like I’m missing something, which is definitely possible. In which case, a quick hint/point out would be appreciated.

I don’t see how this reply of yours does any help for both of us.

specifically, I noticed in both and SEOPress PRO, there’s this identical line in both of the plugins.
return ComposerAutoloaderInit91ca29c4ec10ca5036046c6edbce4ea4::getLoader();

Line exists
In CF7 Google Sheet Connector
cf7-google-sheets-connector/lib/vendor/autoload.php
In SEOPress Pro:
wp-seopress-pro/inc/functions/google-analytics/vendor/autoload.php

Hi,
tried the reinstalling but it doesn’t solve the slow loading speed.
in fact, even without the PRO plugin, it’s already slow.

Please advise next step.

the non PRO version is 1.0.8.
there’s no update prompt in either PRO or non-PRO plugin, so I assume they are all at the latest.
I only have 26 items (serial #s).

A fresh install would delete all my serial #s, no?
