Any solution please.

 

any custom module installed?

 

No custom module installed. It was a fresh installation.

 

well, then only replace theme files using fresh one, both admin and frontend panel.

 

i have not changed any files....all files are original which comes with magento....

 

as far as the parse error, if you have uploaded using ftp, then uploading again should resolve the issues. Though don't re-upload everything, only theme files, including admin

 

When prompted, you can change some of your code?
