Thread:Talk:Semantic MediaWiki 1.8.0/Errors in debug mode

Upgraded to 1.8, and I'm getting a lot of php debug messages. I wasn't having problems with 1.8b2, but it's possible I started the wiki with 1.7 and then went to 1.8 without upgrading the databse through smwadmin. Can't remember.

I get "Notice: Array to string conversion in C:\folder\extensions\SemanticMediaWiki\includes\storage\SQLStore\SMW_SQLStore3_Writers.php on line 383" when saving pages (displays at bottom of page), and occasionally also getting "Warning: Cannot modify header information - headers already sent by (output started at C:\folder\extensions\SemanticMediaWiki\includes\storage\SQLStore\SMW_SQLStore3_Writers.php:384) in C:\folder\includes\WebResponse.php on line 38" which breaks the page.

On some pages I also get "Warning: json_encode: recursion detected in C:\inetpub\wikiwhereis.com\live\includes\json\FormatJson.php on line 48" at the top of the page.

Strangest part is it doesn't always do it.

So did I do something wrong? Should I do the delete all, and then restore?
