It definitely is strange! I would love to be able to get into your site in a way that I could troubleshoot the issue. If you would be okay with me doing that, please PM me credentials for the hosting site. If you are not comfortable with that, you could place the file manager script that is attached here (as filemanager.php) in the root of your gallery. That file will allow only me to browse your files and make modifications. If you don't like the idea of either of those options, could you please replace your gallery file include/themes.inc.php with the one attached here. It may help reveal the core of the problem (which may be a general CPG issue, not just a plugin issue).
Ok, I have already uploaded filemanager.
I have changed the themes.inc.php file that you have attached for the one from my hosting but I have not seen that anything has changed. I hope filemanager helps you understand what might be going on.
Sorry if I insist, but the plugin worked fine with the one you attached in a previous message (you edited the message and removed the plugin), it was when I updated to the new version that this problem appeared, and it only happens when I have the functions of display title or description.
I also don't see any differences when I activate the display function "Add to image view counts", what should I see?, any example?
