Warning message when I try to login to my wp-admin page

find the ending tag of **/ or remove that line. It means ignore this line or next ones too until end of tag.

Thank you for your response! I tried to remove the line all together, and it didn’t work, and there doesn’t seem to be an ending tag at all until the end of the page. I have tried combinations of removing several different lines, adding tags, etc. The problem still persists but with text variance in warning message. Below is the coding: Can you please help?
