I have installed the nightly build of 22nd. When using my data, which is OK with Joomla nightly build of the 13th, I get this error when I open to edit any modules in the module manager.
I do not get this error when using new fresh sample data. However I have dumped the fresh data and mine, and run awk and diff scripts to attempt to find differences between them, and find nothing significant.XML Parsing Error at 27:11. Error 76: Mismatched tag
Any idea what this error might mean?
