You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'key DESC LIMIT 0, 20' at line 1 SQL=SELECT * FROM mmfc_pannoniacup_competitors AS c ORDER BY key DESC LIMIT 0, 20

same applies on each DB-Query in frontend, but data returned is ok:

No valid database connection You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'key AS numlinks FROM mmfc_pannoniacup_competitors AS a WHERE (F5F = 1)' at line 1 SQL=SELECT key AS numlinks FROM mmfc_pannoniacup_competitors AS a WHERE (F5F = 1)
