Problem with right sidebar

On my blog https://techblog.dotcoy.com the sidebar does not show or sometimes when it does it shows up at the end of the posts… but when I click on an individual post the sidebar returns to the relevant place. Pls. help.

Let me know if you need any additional information.

Tried clicking on an individual post, but nothing changed.
Anyone else have any idea?
I didn’t change anything, could it be thru wordpress? My theme? Or maybe I got hacked?
Thanks for trying to help!
Anyone else?

HELP!!

I wanted to put something in my sidebar and just clicked a few xxxx on it so could go and see where would show up on my side bar think deleted something by accident as when went to my site got this message:
Parse error: syntax error, unexpected ‘?’ in /home/affilia5/public_html/Rosettagrieco.com/wp-content/themes/mandigo-14/sidebar.php on line 38

and the sidebar had disappeared.
I removed the XXX but still no sidebar – help what do I do – guess that will teach me to make sure always copy and paste into notepad first!

Can someone please tell me what to do?

Thanks

Get a fresh, unaltered copy of the sidebar.php file and upload it to your server.

And do NOT edit ever any file with that idiotic online theme editor.

OK So Where do I get a fresh unaltered copy of the sidebar.php file?

Thanks

At the place where you got your theme. Download it again, unzip, upload the unaltered sidebar.php.

Sorry to be a pain, new to all this, bit more specific, step by step don’t want to muck it up again.

Thanks for your time and help

That was step by step. Follow this: Themes#Adding_New_Themes – except that you will upload ONLY the screwed up file into your theme directory, not the whole theme.

Hi
I have done it but the sidebar looks a complete mess now?

There is something wrong with your widgets code – either switch to another theme or contact the theme author. Eventually, don’t use widgets until you figure out what is wrong.
