TYPO3 Core

class.t3lib_tstemplate.php tries to store hash values with 21char String as identifier. Since table definition is for this field is 20 chars, this causes an error (see attached image)

have a look into your cache_hash table, there only the entry "TMPL CONDITIONS - AL" (one missing L) as entry.

The error will be shown, if you have SQL Debug enabled and mysql in strict mode (I don't know what will happen in other databases). I got the error first after installing TYPO3 on a fresh XMAPP package on Windows.

Note:
Other solution would be to change the identifier char, searching for any occurrence of the string:"TMPL CONDITIONS - ALL" was not successful, so it might be used in other places as in the core. If it is not used anywhere, the storing of the hash could also be removed from the core.
