WP-Optimize 3.2.5 not caching pages

@webpart Could you please try to purge the cache from WP-Optimize > Cache then Preload the urls and check if it preloads the urls?

When running Preload it gives the following message: An unexpected response was received.

In fact, it does not preloads the urls

@webpart It gives preload error message for the first time, if you click the preload urls button again it will preload the urls fine.

I have the same problem after updating to 3.2.5
I purged page cache and ran preload. As usual, it gave message “An unexpected response was received.” The preload loaded some pages, then it stopped and after I refreshed the WPO page, all cache pages were cleared. This happened in both my development and live sites. I finally have to revert back to 3.2.3.

After the message, clicking the preload button again appears to do something but doesn’t actually load any urls.
Also, clicking on pages on the website does not cache them, unlike version 3.2.3 where everything works fine.

@webpart @francoc30 We are looking into the issue, please rollback now to 3.2.3 version, as soon as the new version is released we will update you.

In view of others’ comments on extra previously unknown files under
/wp-content/uploads/wpo, I want to remove all files under that folder. They remains there even after rolling back to 3.2.3. Will such removal adversely impact the functions of 3.2.3?

@francoc30 No it won’t affect the functions of 3.2.3 you can safely delete the files.

I would like to confirm that the problem I reported here is resolved in version 3.2.6.
