Hi,
I have a gallery and the thumbnails are showing but when you click on them, nothing happens. This is a new problem - it worked until recently. I have updated Joomla! to 3.9.3 and PHP to 7.2 recently but I don't know if this is related. I did try reverting to PHP 7.0 but I still have the problem. My Simple Image galleries are still working on other websites that I've updated at the same time.
I have read through the forum and found a few posts with a similar problem which mentions jQuery loading more than once.
I have uninstalled all unused plugins and disabled jQuery on all the slideshows I am using.
I can't find a place to disable jQuery in Simple Image Gallery (I am using the free version).
I also tried loading jQuery Easy but I find this difficult to understand.
Here is my gallery: rascarrelbaylodges.co.uk/index.php/gallery
Thank you for any help you can offer.

Thank you so much Fotis you are brilliant! I hadn't found that one. Now the images are popping up :)
