Style Problem


Well-known member
I imported a new style from the styles forum on here titled Social which works great, but I now have this error coming up whenever I attempt to modify the default style:

unserialize() [function.unserialize]: Error at offset 0 of 10 bytes

It's not the new style that's at fault - I installed it to try it, wasn't keen, deleted it and now it doesn't matter which style property I click on in the default style I get this error message; the list of style options appears OK but try changing them and *boom* this comes up. The forum is working OK, there's no problem there, but can't make any changes unless I go to the CSS files which is a nuisance. I'm just wondering if the default style has been corrupted; if it has is there any way to restore it?

It's possible. You can import the master again by visiting /install/ and clicking Rebuild Master Data. Then create a new style and delete the old one to remove any additional style customizations:

Admin CP -> Appearance -> Styles

OK tried that and got this whilst trying to rebuild the master data:

It looks as though installing that style has caused duplicate entries - how can I get rid of them? I don't want to do a full install as it would mean losing everything and if I back up the database and reupload it the duplicate entries will still be there.
If I upload a different style - set it as the default, delete the old 'default style' (if that's possible) and then go back to rebuild master data do you reckon that will work?

That is a strange error - not one I've ever seen before. Can you submit a support ticket via the customer area with admin and FTP access details? (And phpMyAdmin if you have it.) I'm going to have to dig into the database for this one. :)

I'd just like to say a huge thank you to Mike for sorting out this problem for me - it simply illustrates a level of support that is unsurpassed and if anyone needs a reason to switch to Xenforo (other than the fact that it is the most amazing forum software this side of anywhere) then getting this level of speedy support should swing it for you. Best move, best purchase I have made to-date.

I have a smilar issue which should not occur when I do a new install of xenforo. It as passed all xenforo requirements. I have followed the instructions carefully, created a new database over and over again, but when I go to install this is what I get:

I have put a support ticket through, any ideas what the issue might be?
Sorry for hijacking the thread. Even i have the same problem as reported in Thread

Anyone got this fixed?

I have opened a Support ticket - XF-3AB45C73 , but no response yet though!
