404 errors on page save / publish

[rst]

Hello,

All of a sudden I started getting 404 errors on my site. Each time I add an image to the textarea and try to save/publish a page, I get a 404 error and the link it generates looks strage domain.com/admin/page/edit/?&id=3114

Also, I am getting another 404 error when I try to use autocomplete function on a field. It was working correctly until a couple of days ago, and just not sure what it could be?

I upgraded to the latest version of PW, that didn't fix it.

Any help appreciated, thanks!

Ask your hosting provider to see if a mod_security rule is being hit.

Look into your webservers (Apache?) logfiles. In error.log you can most likely find the error

I have the same issue. I think the problem is with this part of the query string 

&status%3C2048

The search string works without it. I can't see any way to change that part of the query string in field settings.
