Fatal Errors on Dashboard and Plugins

I have this error on my Dashboard under “incoming links”, “Plugins” and “wordpress development blog” –

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 30720 bytes) in /home4/lajollam/public_html/wp-includes/class-simplepie.php on line 3434

When I click on “Manage Plugins” I get this error and nothing else –

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 7680 bytes) in /home4/lajollam/public_html/wp-includes/kses.php(413) : runtime-created function on line 1

I have absolutely no idea what to do. The website appears to be ok. In order to upgrade WordPress for some reason I have to disable all of my plugins but I can’t do that because I can’t manage them.

My website is https://www.lajollamom.com
