I am converting a site from Joomla 2.5 to 3.9. I have successfully converted the Joomla core and Comprofiler. Now I am having a problem with CB Gallery. The attached snip shows what the Gallery looks like at the moment. The thumbnails are square, although the original images are not. When I click on a thumbnail, it brings up the original image in the correct format.

In 2.5 users were limited to 4 images. I do not understand what the thumbnails containing a "?" are. Nor do I see how to edit the gallery.

1. How can I correct the aspect ratio of the thumbnails?

2. How do I get rid of the thumbnails with a "?"

3. How do I edit the gallery?

I have discovered that when I install CB Gallery, it creates a new set of items in #_comprofiler_plugin_gallery_items. These are the useful one. It also leaves behind the old items. When I delete the old items my problem with the ? photos disappears.

A fresh install of CB Gallery took care of the problem of not being able to upload new files.

That leaves me with the remaining issue of the squished thumbnails.

Thanks. I agree that it was migrated twice. I did NOT do this. I verified that there was only one copy prior to installing CB Gallery and then installed it ONCE. Afterwards there were two copies.

With regard to the thumbnails what does the drop-down box labelled "Maintain aspect radio" on the thumbnails tab of the CB Profiler Gallery tab mean? I was assuming that meant maintain the profile of the original image when creating the thumbnail. I will go ahead and modify the CSS.
