DISASTER with CSS and save

so, several months later i catched same isseu as before..

it is the saving issue

i pressed close the script

but css asked to save template

but no changes were made to template

i bressed go back – then i pressed to save template

then no window appeared

then i press close – without saving

and that happened next:

fortunately all files went back as visible and looks like they are in noirmal condition after CSS was restart

also i cant name my threat properly – this site just blocks to post
