Cannot save Website Settings: "The form was not saved because 1 error(s) were found", but no visible error message

[acano]

Hi everyone,

I’m currently running OJS 3.4.0-8 and I’m encountering an issue when trying to reorder or modify custom sidebar blocks (customBlockManager plugin) via the Website Settings > Appearance > Sidebar Management section.

When I try to save, I get the following generic error message:

“The form was not saved because 1 error(s) were found. Please correct these and try again.”

However:

• No red error is shown on the screen
• No invalid fields are highlighted
• The browser network tab shows a 400 Bad Request response from:

bash

CopiarEditar

PUT /redi/api/v1/contexts/1

• The payload includes custom blocks like menu-lateral, relaredi, and indexacin, all of which exist and work fine.
• The plugin settings for these blocks (enabled, blockContent, blockTitle, showName) are all present in the database.
• Removing all blocks but one still causes the same error.
• There is no useful error output in the Network > Response, nor in the PHP log or browser console.

I also tried resetting showName to '1' for all custom blocks via SQL (some were NULL), and still nothing.

Question

• Is there a way to enable verbose error output on API PUT requests?
• Is there a known validation rule that could be failing silently for custom blocks?
• Has anyone else experienced this when upgrading from 3.3.x to 3.4?

Thanks in advance for your help!

Hi @acano,

It’s likely that the problem is coming from mod_security, or another similar security tool on your server, before the request even gets to OJS. I’d suggest double-checking if you’re using a tool like mod_security, and if so, check to see if it logs this request as being blocked.
