Need Help ! my blogger HTML is Thawed . Cant Save anytrhing in HTML


yesterday i was editing some css codes for h2 h3 and h4 . after changing i pressed save theme . it started saving and was successfully saved. there was no error but when i looked at my blog the changes were not made. so i returned to the theme and edit html and than Tada. it was reverted back as it was…

it thought it might be a temporary problem so ignored it. i did it again and the same happend again . i became curious and tried another thing like adding keywords in meta and then saved again it was successfully saved but when i returned and saw it, it was also reverted back.

so basically i am stuck in this i think. the changes i make in layout they dont revert back only html settings are not saving . i tried to clear cache cookies , history changed browser . nothing Helped. Here is my link to the blog.

Muhammad bro please help or any body who can please help me.
