Hi @NufanBalafif,

This type of error suggests that you may want to check your PHP error logs. You and then report back on error messages found here on the post.

Thank you for your response.
I checked the error_log and it didn’t show any errors, just this:
[12-Feb-2026 00:02:38 UTC] ojs2: 404 Not Found
[12-Feb-2026 00:02:38 UTC] ojs2: 404 Not Found
[12-Feb-2026 00:02:45 UTC] ojs2: 404 Not Found
[12-Feb-2026 00:02:45 UTC] ojs2: 404 Not Found

In the custom block manager, if you only write/attach a link, it can be saved. However, when you insert an image, whether internal or external, it can’t be saved and just loads.

Hi @NufanBalafif,

Before hitting the “Save” button, try opening the web browser’s developer tools to the Network tab. Check to see what the response from the server is when you attempt to save the page. I suspect something on your server, e.g. mod_security, is interfering with the request getting to OJS due to the contents of the form.
