On the website http://www.imkersverenigingblaricum.nl (J1.7) I use the template Purity ii. Initially it all worked perfect, but some time ago, there suddenly appeared a narrow white bar above the menu and the background of the articles turned white (was yellow). I reinstalled a Back Up and everything worked fine again. But now the problem appeared again, and I dit not changed the template.
Does anyone know how this happens? In advance thanks for your help.
