Two months ago my feed was ok but now suddenly does not work any more. I haven't posted in these two months, just upgraded some plugins and maybe the wordpress itself. I tried to disable the plugins, activating them one by one and also installed some feed fixing plugins but nothing.
Feed validator says:
line 38, column 1: Undefined item element: a
line 38, column 276: XML parsing error: <unknown>:38:276: mismatched tag
Error on line 38: The element type "img" must be terminated by the matching end-tag "
Feed itself is here:
Thanks a lot!
