Template Creator blocke on Joomla 2.5

Hello everyone,

I had a problem on a site Joomla 2.5 for the operation of the Template Creator. I used version 3.3.5 and sometime ago, worked perfectly.

For sometime the component is blocked (see attachment) and I had no chance to get ahead in the job.

I updated the component to the current version (3.5.3) and, as previous experiences, I asked my hosting manager to disable ModSec for that site.

Unfortunately the result was the usual with the aggravating circumstance that the screen is not usable (see attachments 2).

Can you help me?
