Hi!

I'm making a new website with Wordpress on it, I'm having trouble getting it working. I was told this is because jQuery runs twice and after I removed a jQuery the proper one was loaded too late so it doesn't work. It probably has something to do with wp_head() not properly calling jQuery. I hardly have any PHP experience, and everything I tried did not work. Is there someone here experienced with Wordpress and able to fix this problem?

Please let me know! Thanks.

what have you done to do after installing wordpress?

You're not supplying enough information. I recommend posting something more detailed in the .org support forums:

You'll need to provide more information than you have, but you can start with checking the source output in the browser to make sure the jQuery library is being included before any calls are made to jQuery objects.
