all images on the website pages had gone after the update which we made yesterda

Hi @olgayoga

Looking at your page, there are a few javascript errors that could be the cause.

WP 5.5 included a major update to jQuery which a lot of plugins use, so one of those plugins could be causing a jquery error which will then in turn cause FooGallery to not load. More info: https://wptavern.com/major-jquery-changes-on-the-way-for-wordpress-5-5-and-beyond

Things you can try immediately: goto FooGallery Settings -> Advanced Tab and enable ”
Custom Ready Event” which gets around jquery ready errors caused by other plugins. You can also try deactivating the cache plugins you have installed to see if this solves the issue.

thanks. now it’s solved!
