I spent a good deal of time today tracking down a bug that occurred in my sandbox after adding the devel module when i ran cron.
“An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows.” :-
i checked and reenabled a submod in sand that was still on in prod. the error went away. all i can tell you is have a testbed.
since i am adding content and working on layouts now, i have run into some of the limitiations of blocks. so, i’m working with views and learning how to display them in panels. looks like this is the route to take. will add more about this later
