[TYPO3-RTE] Problem with Installation

[Phil]

Hello,
I have already a large problem with the pure installation of the extension.
I installed in the following order:

    dynaflex_1.11.0
    graytree_0.1.1
    moneylib_1.2.1
    static_info_tables_2.0.5
    tt_address_2.1.0
    commerce_0.9.2
    commerce__germantax_for_ap_1.1.0

Now, if I want to add a product, I get this error:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result 
resource in /var/www/typo3_src-4.1.3/t3lib/class.t3lib_db.php on line 783

Fatal error: Cannot use string offset as an array in

on line 870


Can anyone help me please?
