I just recently checked my website http://www.homeopathy.lv and noticed that the slider had disappeared and the galleries section’s preview icons had turned into invisible and huge white blocks (http://homeopathy.lv/en/galerijas/). I tried to reinstall Tempera, update all plugins and disable/enable slider in the settings, so far no luck.
The site has a JavaScript error related to the ‘nice navigation’ plugin (most likely due to changes brought by WordPress 5.5). This can affect a lot of functionality, including the slider.
Check if that plugin has a compatibility update or if the author is working on one, or look for alternatives.
