Firstly thank you, EE is compared with so many other CMS’s a breeze to update however this time going from 1.51 to 1.6 we have experienced issues.
The wiki is spitting out error messages before rendering content concerning 255 character support, reverting to the file system/wiki/mod.wiki.php from 1.52 fixes the problem.
The search is another matter however.
The file system/search/mod.search.php throws up an SQL error and refuses to render the page. the same file from 1.52 works but throws up errors header as obviously the database structure/file system dependencies have been amended on upgrade.
So the question is, before I go posting details of the error messages, is, has EE 1.6 raised the stakes in respect of of acceptable version of MySQL or PHP, as I have a feeling this may be my server rather than EE?
