A collegue inadvertantly created a link to a website.
While trying to delete this link the Hipo is hanging at: "Create Links HIPO Progress 20%".
Any ideas as to why this may be happening? The Linked site is pretty big.
The HIPO is probably trying to remove the URLs from the Linked Site after the site gets moved to the trash (i.e. when the link is removed).
If there are no errors being generated in the error.log, I'd leave the HIPO to complete. Otherwise, if you do get an error (most likely it'll run out of memory), you may need to contact Squiz Support to get the link removed manually from the database.
i had a similar problem once (stuck at 10%) and it was because one of the pages was locked.
after i released the lock the hipo was fine
