I installed Uniserver Zero XIII this morning (latest version). I have no experience with Uniserver so it is new to me. I put my codes in there and ran localhost link to my local website...this is message I get.. What can I do to fix this? I have tried googling to find solution but unfortunately it is too general to figure it out. Hope one of you can help me with this issue. Thank you in advance! Icy
