Thank You Thosrtanner the fresh install solved it not really: "[W] QIODevice::read: device not open" is not shown at the beginning. But with running implemented Loot to sort plugins espacially with the unofficial patches the message shows again. Edit: Now I have little idea what this message mean. After running the implemented Loot you got usualy a report in an extra window. I got no report, though Loot seems to work properly. Reinstalling with a new download didn´t fix it.
When starting Mo (version 1.3.8) I got following warning in the window at bottom where the "starting protokoll" is listed: 08:54:27 [W] QSslSocket: cannot resolve TLSv1_2_client_method 08:54:27 [W] QSslSocket: cannot resolve TLSv1_1_server_method 08:54:27 [W] QSslSocket: cannot resolve TLSv1_2_server_method 08:54:27 [W] QSslSocket: cannot resolve SSL_select_next_proto 08:54:27 [W] QSslSocket: cannot resolve SSL_CTX_set_next_proto_select_cb 08:54:27 [W] QSslSocket: cannot resolve SSL_get0_next_proto_negotiated 08:54:50 [D] localization file qt_de-DE not found 08:54:50 [D] localization file organizer_de-DE not found 08:54:50 [D] localization file bsaExtractor_de-DE not found 08:54:50 [D] localization file gameSkyrim_de-DE not found 08:54:50 [D] localization file iniEditor_de-DE not found 08:54:50 [D] localization file installerBAIN_de-DE not found 08:54:50 [D] localization file installerBundle_de-DE not found 08:54:50 [D] localization file installerFomod_de-DE not found 08:54:50 [D] localization file installerManual_de-DE not found 08:54:50 [D] localization file installerNCC_de-DE not found 08:54:50 [D] localization file installerQuick_de-DE not found 08:54:50 [D] localization file NMMImport_de-DE not found 08:54:50 [D] localization file previewBase_de-DE not found 08:54:50 [D] localization file proxyPython_de-DE not found 08:57:57 [W] QIODevice::read: device not open I didn´t recognized any issues yet. But as a beginner I´m little unconfident. Is this a warning I could ignore? Or is there some troubleshooting to do? i the last case I like to know, what I should do.[]
