Can’t Save the settings?

This may be tricky to fix since there’s no error message or anything else that could help identify the cause. Could you perhaps click the “Save Changes” button and then just leave the tab open in the background for 30 minutes to see if anything else happens?

When did this problem first appear? Was it immediately after installing the plugin (i.e. the plugin never worked properly), or did it start happening after installing another plugin, or an after an update, or when you changed certain settings?

Usually I would also recommend checking the PHP error log for fatal errors, but if there’s some script that keeps running forever, it might not actually log anything. It might still be worth a look.

Thank you for your quick reply.

I tried to wait and it ends in a 503 error: Service Unavailable, does that help?

It helps a little bit. It shows that the problem is most likely on the server and not in the browser or some piece of JavaScript.

Do you have access to the web server logs? They might provide more information about the “service unavailable” error.

I noticed this in the error logs:

x – removed for safety

The first entry looks relevant. It seems that the server is running ModSecurity and it is configured with a request body size limit of 128 KB. The plugin can sometimes exceed that size if you have a lot of plugins and/or menu items. In some cases, the menu configuration can be 200 KB or more.

I would recommend either significantly increasing that size limit or adding an exception for the plugin settings page (if ModSecurity supports that).

Thanks Janis, I’ll discuss this with my hosting as I don’t think I can adjust this myself.

Dear Janis,

It has been increased to 13mb and still I get 503 service unavailable after a while… any idea’s?

13 MB should be more than enough for this plugin. Did anything change in the error logs? Are they still showing the same errors when you try to save settings or is there something new? If it’s the same error, does it reflect the increased limit or does it still show the old one?

Dear Janis,

CUrrently I get this error:

– Removed for security

The first message still says that the configured limit is 131072. Assuming that’s in bytes, it translates to 128 KB and not 13 MB. Are you sure the host changed the right setting? Maybe they increased some other limit by mistake.

Dear Janis,

Thank you for your quick response. I’ll send it over to the host again!
