I have just upgraded to Moodle 2.5 and there are several glitches:
a) The TinyMCE editor does not appear even in collapsed form even though it is enabled, eye is open, etc. I just get a plain text field with all the HTML code etc. Also there is no "edit hand" just a small cog.
b) Once I get off the Home page and into the individual course some of the links e.g. users, site administration, etc do not work except from the Home page.
c) I do not seem to be able to get the Home page to have a self- enrollment or Paypal enrollment link so students can enroll themselves.
