kormanlo again pmed me and said these:
"When I opened the file you sent, it displayed a blank page in Log viewer but there was also a hidden html document near it. I opened it by double clicking and it opened it in firefox (ahmetgns thinks the html files are associated with Firefox in kormanlo's computer) and I could read them."
So I think this is a log viewer problem but if log viewer uses the Internet Explorer to display logs, I demanded kormanlo to open that hidden file near the .ple file in Internet Explorer itself. I hope he replies here this time, not pm me
and we understand if the problem is caused by Internet Explorer itself.
