Thread:Project:Support desk/Installing extension on 1.19.1/reply (2)

I tried to install the extensions.

The following lines are the errors I got in the Apache error log for each extension.

AddHTML PHP Notice: Undefined variable: replaceFlag in .../mediawiki/extensions/AddHTML/ExtensionClass.php on line 269,

Any idea? Is there other extension that can replace those extension?
