This problem happened after I did routine plugin updating at WP admin > plugins. Then Ike said this:
“Please take a look in the WP admin page at Forum > Plugins – to see if anything needs updating”
So I went to WP admin page > Forum > plugins. It appeared a number of plugins need updating. I updated them and it showed “error–plugin already updated.”
I checked the forum and tried to get into a topic and it returned “Invalid query”. I have not seen any change in anything.
I feel stuck and like I am wasting my time. I would appreciate if Brandon would take a look. It seems to me that the experts here, who know the forum technology, would be able to figure it out much faster than me. What do you need from me?
