Hello @stathis_k91,
I’ve tried to test some plugins that provide the post grid block(s) and was unable to replicate it on my end, and no similar issues have been reported by other users to this moment.
Please explain to us step by step how we can reproduce the issue so we can recreate it somewhere other than your website. You can upload your files to one of the following online services:
https://postimages.org
https://drive.google.com
https://wetransfer.com
Also, kindly provide us with your system environment information. To do this, please go to WP Dashboard > Tools > Site Health > Info Tab and click on the button Copy site info to clipboard. You can send the information as code here or upload them to https://pastebin.com/ and get an exclusive link: https://i.postimg.cc/fbjtkFyJ/image.png(you can remove your email address from the content).
Before sending these, please make sure that:
Everything on your website is running the latest versions (WP, theme, plugins).
If possible, perform a basic troubleshooting checkup method and make sure the issue is related to our theme or plugin(s). To do this, deactivate all other plugins then activate them one by one and check for this issue. Continue doing this until you find what product is causing a conflict with our product. Then provide the details as explained above.
Note: If you have any cache plugin or server cache(CDN / Browser Cache and Cookies and …), you need to clear its cache contents or disable them to see your changes.
Please keep us posted.
Thank you,
Best Regards
