Can't add/edit blocks

So far was really liking Composr want to go with it for my ATS/ETS2 VTC home over WP that every other VTC seem to use wanted to use somethign to make us stand out a bit more so thought to try Composr..but have run into a problem after trying to add a block or remover or even do nothing when in Zone Editor (any page) when I hit save get a 404 Not Found. This is the only error I have go anywhere but seeing where it is it a problem…

The address it go's to after clicking save is..same for what every Zone I try to edit
the one thing comes to mind is as I'm on a free server some PHP or info is not getting done right or could be just some setting I dis wrong or missed any and all help is welcome..dont want to go to WP :(

Can you attach a screenshot of the error?

Also please check the web server error log and see if anything useful is in there, I am wondering if ModSecurity is triggering this.

I think you are right on the ModSecurity was looking over some of my hosts support forums and seems on free hosting only allow max of 3 inline links looking at the 404 error page address kind of make me think that so ether have to see if they can turn that off for my site or look for some other host if that is the issue.. But also seeing as that was a 403 error and I'm getting a 404 I could be off the mark lol

Can't show server error log as can't find it that is also something els that is missing

Screenshots though they don't show much..page trying to edit (same error for all pages though) and error after clicking save


EDIT: have added screenshot of Resource Usage Overview log page (one of the only logs it gives me) that seems to also point to a limit problem maybe's

Right, unfortunately free hosts often impose limits we can't reasonably workaround.
ModSecurity (if this is involved here) is a particular pain because it hides it's error messages, so errors look like regular 404's or 500's or whatever ModSecurity is configured to show - that makes it hard to debug, unless you know how to analyse the Apache error logs.
