Try white space.
I know and i will fix it with overflow hidden just saying its a small bug as anyone can come to your site and spamm like this making it look like broken.
It's comming from osclass core. Osclass has session funcitons to remember last parameters (on previous page) so when your validation at publish fail, value you have entered are correctly restored.
I don't get it. You mean this is osclass core bug or not bug at all? because i have never seen that and its shouldn't be like that.
When user posts a listing and see his desired location filled already he will leave it like that and then his listing will not have location
Should i post it to osclass forums to fix the bug?
