I upgraded my database from MW 1.31 to 1.33, but I am having problems with the Arrays extension, specifically seeing strip markers (e.g. UNIQ--nowiki-ArrayArrayArrayArrayArrayArrayArray6-QINU) in the rendered page and the following messages:
Notice: Array to string conversion in extensions/Arrays/ExtArrays.php on line 1216
Warning: Cannot modify header information - headers already sent by (output started at /extensions/Arrays/ExtArrays.php:1216) in /includes/WebResponse.php on line 72
I'm not sure if this is related to other problems folks have posted. Any help appreciated!
