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.
XML Parsing Error at 27:11. Error 76: Mismatched tag
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.
Any idea what this error might mean?
