This is the problem for arcaf.ca hosted on wordpress.com. I was doing WordPress version upgrade.
Since that moment I cannot enter the dashboard -
Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 122880 bytes) in /home/arcaf/public_html/wp-admin/includes/dashboard.php on line 550.
I removed some files to make more free space - it didn't help.
I use my miregia account to report the problem.
Thank you, Andrew
The blog I need help with is miregia.wordpress.com.
