If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
404 error means that the link you have provided is not there.
on your links page I can see 4 of these and 2 that are OK.
may I suggest that you edit the 4 that don't work. I presume you made these with the text widget. In that case highlight the heading to be linked again and select the link editor from the edit menu. This will bring up a dialogue box and one of the options will be to link to another URL. Type in the URL and OK. That's it.
Get back if there's something that you need help with.
