Fatal error WPMU Dev

Hello

I updated my payment info because WPMU required it, but on my wordpress dashboard WPMU said it was still waiting for the new info, so I clicked "refresh data" or something similar.
Now I have this error: Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4666 bytes) in /home/username/public_html/wp-includes/wp-db.php on line 1846

Any help is appreciated
Thank you
