I know this issue has been mentioned before but I thought I would share my experiences with this issue when trying to upload a log contains a record from SP5BGG.

In my case the issue appears to be due to his name being recorded as >tadek< on hamqth.

This gets encoded in the CQRLOG as &gttadek&lt (I removed the ; delimiters here to stop the encoding getting processed by HTML) and it is this encoding which seems to be the issue with uploading to clublog.

The solution in my case was to manually edit his name to remove the encoded >< signs, manually import the ADI log into clublog, wait for the log to process and then I could upload normally again.
