XF 1.4 Editing template causes error

[Chromaniac]

I had to migrate to a new server which used a different control panel. As a result, I had to migrate manually. I am not sure what went wrong but I cannot now edit templates from XenForo backend. Here is a screenshot of what happens when I try to edit a template. The page gets stuck. The head expands and it hangs. On refresh, the changes are not preserved.

Forum is working fine otherwise.

If it only happens when editing a template, it's almost certainly mod_security (or similar) related. They tend to have rules that trip when HTML is submitted.

thanks. this is namecheap btw. i have filed a support query. assuming they would not change the settings for me, i guess i would be looking for another host!
