There's no list of non-SEF URLs. If you have en/products/tansun-rio-ip as SEF URL (either trashed or not), you just can't manually create new entry with the same SEF URL (duplicate). So if it's trashed, it's not being used, but you can't manually create new one. So you can either restore it from trash (so it's used again), or delete it completely and create a new one.

Anyway the www.tansun.co.uk/en/products/tansun-rio-ip seems to be working. What are you trying to achieve with it?

Hi Dajo,

Thank you so much for your help. I don't want the sef URL for this page to be www.tansun.co.uk/en/products/tansun-rio-ip. What I did is create a new sef URL for it www.tansun.co.uk/outdoor-infrared-heater but I didn't put trash the old sef URL that jomsef created (www.tansun.co.uk/en/products/tansun-rio-ip). so now never mind what I put in I cant change it from www.tansun.co.uk/en/products/tansun-rio-ip

Kind Regards

Ok, now I understand. Yes, trashing or deleting the old URL should solve it.

Hi Dajo,

It didn't work. Looks like I am having problems with other url's that won't change either:-
www.tansun.co.uk/en/products/tansun-rio-ip -
www.tansun.co.uk/en/infrared-heating-applications
www.tansun.co.uk/en/general/about-tansun
www.tansun.co.uk/en/news/blog
www.tansun.co.uk/en/technical/how-quartz-heating-works
www.tansun.co.uk/en/technical/benefits-energy-smart

All these have new SEF Url's successfully created i.e www.tansun.co.uk/outdoor-infrared-heater works but the site still shows www.tansun.co.uk/en/products/tansun-rio-ip. I looked throughout all url's/custom/trash etc but www.tansun.co.uk/en/products/tansun-rio-ip does not exist. Why are the old sef url's still showing on some but others change successfully for example www.tansun.co.uk/indoor-outdoor-infrared-heater????

Kind Regards
Neil

Yay!! Fixed it! turning off the cache within Joomsef is now showing all the correct urls
