How to avoid this problem?

When i added adsense code in my forum admin-current theme(Dilber MC Theme by HarzeM)-in html code box,my forum became like this http://www.findallinone.com/forums/ .How to avoid this problem?

 

Your forum became a nice gradient blue?

Or do you mean this problem... http://forums.findallinone.com/index.php?topic=16.0 ?
Center that <td>, change the background of the AdSense to match that blue you have, don't stack two ad units like that...looks tacky and doesn't work (at least for me).

 

I added code here in my admin .
configuration-current theme-theme settings-Theme Options and Preferences-HTML code to be displayed below user info bar
[google adsense code added here(only 1st line of adsense code displayed here,when i had added code here)]
HTML code will be displayed over page content, below user info bar. You can use to add a banner, or make global announcements etc.

I am not able to login in my forum now http://www.findallinone.com/forums/ .Can i change forum default from Dilber MC Theme to SMF Default theme in my cpanel? Can i remove google code through cpanel? How?

 

not above reason,i wanted to place google adsense below user information bar.after placing ,saving, forum became like this http://www.findallinone.com/forums/ .after saving i am not able go to the same page to remove the code.i think it is possible to run the forum by fixing errors throug cpanel only.How?

 

Here's two things to try
1) Check at SMF and see if there is a tool that lets you get into your control panel
2) Look for either a user-specific or global theme setting in your database. You can then use a db tool to go into the database and change it to the other theme.

 

Try this:
http://www.findallinone.com/forums/index.php?theme=2
Then login and change it

 

I am not able to login,because theme is changing ,when i click login option.

 

Is it possible to install new theme as default through http://filezilla.sourceforge.net/ ?

 

Did you try using the shortcut login at the bottom of your forum instead of clicking login at the top? You can see it when you use the link Diether gave you. Once logged in, you may need to click Diether's link again.

Update: After following Diether's link a 2nd time, the login box and everything else is remembering the theme #2, so everything works. Just try the link again.

How to remove it through my cpanel? where is this error in my forum http://www.findallinone.com/forums/ ?

 

Go to your pypmyadmin in your cpanel.
Find the smf_ads table
Press "browse" and then delete the google ads from there
That should work.

 

Your suggestion solved my forum http://www.findallinone.com/forums/ problem ,Thank You.Thanks All.

 

No problem.
