What exactly are ye' tryin' to change madam? Profile image, signature, display name, etc? A bit of additional details will aid in figurin' out what's causin' the error.
Ah, t'is quite alright Ms. I'm pleased to hear ye' got the situation handled. It'd help if ye' put "Please Lock" in the topic's title for it'll be a bit more noticeable to a Moderator/Administrator so they can swoop in and lock this. A mere tidbit for ye'.
