Thread:Extension talk:WYSIWYG/Text gets scrambled on multiple switches between CK and WikiText/reply (5)

If you have problems with page contents when you use buttons source and/or toggle link, then you will most propably have problems with pages if you try to save them after editing page in wysiwyg. Disabling those two buttons will not solve/remove possible compatibility issues between wikitext/wysiwyg modes with your wiki pages. I would suggest you first test wysiwyg and editing modes with simple test page only so that you can see that your setup / browsers are working properly.

In front page of this extension on last line of table "Downloads" (=#6 bundle), you can see MW versions which have know to be working with #6 bundle. You can also see what php and MySQL versions have been compatible with it. If you use some other bundle than #6 bundle of wysiwyg, there are some information available for them too.

This applies to #6 bundle only (version 1.5.6_0 [B551+13.03.2015)): Default setup of downloaded bundle should work.

If you would like to use toggle link (=text link above editor window) you should also have wikieditor (modified version downloaded with wysiwyg bundle) installed and enabled in your wiki, otherwise it will not work. You can disable toggle link in user preferences by deselecting option "Use toggle to switch between wikitext and rich editor".

See readme.md for more information about user preferences (Chapter: "Preferences=>Editing") and sample settings for LocalSettings.php (chapter: "File: LocalSettings.php").
