There was a image sizing issue with WordPress 6.7 release but its been fixed with WordPress 6.7.1.
In order to minimize the cause of the issue and to ensure there is no conflict between the theme or plugins you use:
Could you please try to resolve your issue by deactivating all third-party plugins as well as the default theme to check for any possible conflicts with any of the plugins or themes?
- Do you see any difference?
Can you please send me admin access details and let me check what's going wrong with your setup. There must be some options from the lightspeed cache plugin that should fix the issue.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
On the following lightspeed settings page:
=> hidden link
With the section "URI uitsluitingen" (URI exclusion) I've added the URL "stag/kunstenaar-zoeken/" and I can see now its working as expected.
Can you please try to update the same setting on your production site and add the URL "kunstenaar-zoeken/" and save the settings and check if that help you to resolve your issue.
