After Upgrade
 

i was using 3.6.9 but today i installed 3.6.10 after installing it's ask me about revert then i did revert after revert my style footer and header images are missing

Redo the changes you had made to these templates.

how to reload the changes

should not have reverted.. now you have to edit your template again. :(

how do i edit plz explain

edit your header and footer template inside adminCP styes

but what edi t which line in header plz tell me

You need to add it yourself, we can't do it for you, we don't even know how it was before.

Did you edit the header/footer originally for a modification you installed? Just go find the modification thread and read the installation instructions again and I'm sure the template edits will be explained there.

(Or, if you have a test board setup, look at the templates there.)

Contact the person that has created your forum skin / design.

or if you have a backup somewhere then import that and start again..

if i remove my Style and add again then i will works fine
