I have a vanilla install of Mingus WordPress with no plugins, and no categories setup. I tried the blogging by mail, and my email was processed, but when I went to the front page of my blog, I got the following error where the category should be:
Warning: Invalid argument supplied for foreach() in /home/geodog/public_html/strangelove/
wp-includes/template-functions-category.php on line 65'
When I went to the editing page to correct it, I found the following error under the categories column:
'Warning: in_array(): Wrong datatype for second argument in /home/geodog/public_html/strangelove/
wp-admin/admin-functions.php on line 41'
I checked the checkmark next to General, clicked Save, and the error when away. However, when I tried blog by email again, the error happened again.
I saw some posts about this in the forums, but no solutions suggested. Anybody have any ideas? Anything I can do to further debug the problem? TIA
