Thank you for sharing these details.
1. Missing images:
Your website is using the "Site Acceleration" feature from the JetPack plugin, which loads the website's images from its own server/CDN:
hidden link
If you still see any missing images, try deactivating this feature, and if the issue is fixed when this feature is disabled, consult the JetPack plugin's official support and documentation, for the most optimal settings.
2. Cached or old content showing:
Your website is using the "SiteGround Optimizer" plugin provided by your web host SiteGround.
In case, you see that some of the pages are showing the older/cached content, please make sure to clear all involved caches from this plugin's settings.
Note: As the cache is already being controlled by the "SiteGround Optimizer" plugin, it is a good idea to disable the "Cache View" option from the Toolset's "Views" blocks.

3. Error when trying to use the "Customize" screen:
The Elementor plugin is also active on your website.
We've recently identified and escalated this issue where the "Customize" screen shows the error when Toolset and the Elementor plugins are active.
A fix for this will be included in the next batch of Toolset plugin updates, and for now, you'll find the patch and instructions to fix this at:

I hope this helps and please let me know in case the issue persists, even after applying the patch.
