De koelvloeistof van de database was bevroren...
Hij doet het nu weer.
For the ones who googled "Got error 134 from storage engine" on a SMF forumOne of your database tables has crashed, it probably is your session table but check if your not certain.
Anyway as these kind of fixes are hard to find due to clutter in google by forums with this error, here are 2 ways to fix it.
1. Log in to phpMyAdmin
Execute: REPAIR TABLE smf_sessions;
2. Start SSH
Log in on MySQL:
mysql -u
username -p
password databasename (change the underlined values into your own)
And execute: REPAIR TABLE smf_sessions;
Done!
