Topic on Extension talk:Poll/Flow

I get this when I use this extension and run rebuildFileCache.php:

PHP Fatal error:  Uncaught exception 'DBTransactionError' with message 'Explicit transaction still active. A caller may have caught an error.' in /var/www/html/includes/libs/rdbms/loadbalancer/LoadBalancer.php:1045

Commenting wfLoadExtension( 'AJAXPoll' ); fixes this problem.

Caching with the poll may be problematic. I'm not quite sure how to solve this. Has anyone else encountered the issue?

Here's a bit more of the trace:

The first error tells about "Database is read-only". Did you put database in read only mode when running rebuildFileCache.php, or did you set $wgReadOnly to true?
