I am working on a trail map for a Non-Profit. Created a few maps last couple of years with previous versions of QGIS and just updated to 2.18. Running a Windows 10 OS.
QGIS loads fine, but when project starts to load get pop up error message with cryptic login requirement with unknown user and password already in place. Of course this is Not valid and will not clear. I do not know for sure what site it is trying to log in to. Program will not load and cycles back to error message.
To the best of my ability it appeared to be trying to access the qgiscloud.com. I did change the default password being displayed with my qgis cloud password to no avail. Have attached image of error message.
