@losviajesdeluciabox usually the issue with users unable to attach photos is because of cache issues, make sure you have cleaned up ALL caches, CloudFlare and CDN if any on your site, then users or yourself if still having issues after cleaning up all caches in the site should go to the forum page and Press CRTL+F5 twice and try again.
The license issue is because you probably need to buy a new license (You are also probably getting a discounted price this time), the newest versions of WPForo and addons require a new license if you want to upgrade to them.
Sorry, but I don't understand. How can I clean up all caches?
I have a new license, I think
