Fix broken navigation:
If your MuraCMS installation suddenly starts having odd navigation problems (top-level navigation changes when you hit a top-level menu item), it may be because you cut, copy and pasted a page under a different "parent id". To move a page under a different parent ID, you should edit the page and use the Change Parent feature instead. Until this bug is repaired by the MuraCMS team you should only cut, copy and paste into the same parent page, then move the copy using the aforementioned tool.
We have a script (available upon request to anyone- customer or not) that will repair the parent id in the path field of the tcontent table. Please send an email to firstname.lastname@example.org and we'll send you the script.
