I Haven't A Clue What I'm doing!

  Well... there was me trying to get a new background on my Spyder's Corner Blog, coz the other one disappeared... so I thought, (don't think Lyn it'll end in trouble...) I'd 'practice' on my digi store blog. BIG MISTAKE!! It completely went black with white writing and a completely different layout with no sign in or design at the top to click on, no little pencil thing to click on if you want to do a quick edit, and no way of getting it back as it was, as there appears to be no 'template'  I can work with, to add things and Ikes La La Land header was replaced with ordinary type and no picture... So I had another 'practice' on another page...followed instructions... very confusing and this came up... another flippin' blog!! where I did manage to add Ikes topper.... how? I have no idea...guess work?! And a bit of swearing. All I want is the same template that's apparently on this new blog put back on my  old Spyders other corner blog, it comes up with, template not supported... what in mangled spiderlegs does that mean??? Still, I feel I can moan here...no body's going to know it's here so I can ramble on til the cows come home! And I probably will!
