Photo Gallery paging not working correctly version 3.0.1

We have a page that shows photos from a specific gallery (which contains thousands of photos). Previously we enabled paging, set limit to 20 and it worked perfectly. Clicking the link to the page showed 20 photos, with page numbers at the bottom, allowing the user to go to the next page of 20 photos until they reached the end.
 

After update, if we enable paging and set limit to 20 the link does open a page of 20 photos from the gallery, but instead of page number links at the bottom there is a "More" button,
 

which when clicked adds only 13 more photos all of which are in a single column, and they are simply a repeat of the last 13 photos in the first set that was shown. There is no "More" button at the end of this new, single column set of repeat photos.
 

Changing the "Limit" number under Paging still give similar results after the "More" button is clicked: a single column of some number of photos that are repeats from the first page.

Setting the "Limit" number to zero or leaving it blank loads several thousand photos (seems like maybe it is actually loading all photos from the specified gallery, which would seem to indicate that it has access to all photos in the gallery)

Strange, paging is working perfectly fine in all my tests. Within the _comprofiler_plugin_gallery_items database table does all your media properly have a "page" column value? As for them being in a single column I'm not sure how that could happen beyond a CSS conflict. Do you have a custom template for CB Gallery? If so please switch it back to default.

Ok, was able to duplicate your issue by causing the next page to be invalid and it'd output the entire gallery again. Am working on a fix for that, but my guess is your paging isn't working right due to maybe the paging values didn't migrate properly.

A new build release of CB Gallery is now available that prevents outputting a More button if the next page is invalid. Should prevent this issue from happening, but doesn't solve the issue of media missing pages, which should've been migrated fine.

Looking for irregularities that might explain the errors we are getting. I notice that the params setting in comprofiler_plugin_gallery_items seems to have 3 types of entries:
 
(It won't let me type the left and right square bracket--is disappears from this post when I submit)
or
NULL
or something like:
{"name":"1762306899082.jpg","extension":"jpg","mimetype":"image\/jpeg","modified":1762308148,"filesize":110304,"height":640,"width":640,"name_thumbnail":"tn9374b7ae97af3d7e70e4bd37cac6aa0b.jpg","extension_thumbnail":"jpg","mimetype_thumbnail":"image\/jpeg","modified_thumbnail":1762308148,"filesize_thumbnail":29999,"height_thumbnail":320,"width_thumbnail":320}

Would this have any connection to the weird photo gallery issue or with the single random gallery photo module sometimes disappearing?

Or is there some way that I can identify a which media are considered "missing" so I can look for that kind of irregularity in the database and makes changes?

And yes, all gallery items seem to have a valid "page" value. All are something like this 1763459793.26615, where the number after the period is the ID for that entry.

We do not use any modified templates. The page is set to Cassiopeia. Changing it to Default did not fix the problem.
 

Please update to latest build release and see if your issue continues. If it does please PM backend super user login credentials and will take a look as I'm not able to replicate your issue at this time. As for the params column it won't have any impact on paging and is fine that older entries are missing cached data.

I was meaning in regards to CB Gallery and not Joomla. Each gallery, and CB Gallery globally, can have a template selected.
