Hi, did you recreate all additional thumbnails?

Hi, please try to download this file:

https://www.phoca.cz/forumfiles/imagefront.zip

unzip it and copy it to your server to folder:
administrator/components/com_phocagallery/libraries/phocagallery/image/ (so the imagefront.php file will be overwritten)

and let me know if you still get the problem or if you have other error?

Thank you, Jan

Thanks for the quick reply
So, I checked settings. I think, I properly configured settings. But after replacing the file, there was no better.
Error persists. Maybe I should make a video screen?
I have an old version of the site, but created a lot of new materials. It is a pity to lose data
Thank you very much!
