So... I had to upgrade joomla 1.5 to 3.5 today. It was much fun :D
Managed to fix everything except links to other articles that are embedded in the content.
Site is multilingual.
Here is original link within content from Joomla 1.5 and how it get's rendered on the frontend:
And here is link that Joomla 3.5 editor will generate:
index.php?option=com_content&view=article&id=80&catid=8&lang=en-GB&Itemid=12" hreflang="en" /en/8-english/80-ester-house-of-stanisic-lu-fi.html
Joomla now requires me to input catid, lang and itemid. Is there a way around this, or some kind of tool that'll fix joomla "in article" links?
