It seems that there are no glitches at all from the beginning to the end until I started query after the installation of a preindexed corpus. There was no response but a blank page, showing no errors too. The preindexed corpus was taken from my server that was taken offline. It was supposed to work well with CQPweb. I met the same problem when I tried the sample Dickens corpus. I am using CWB 3.4.33 and CQPweb 3.3.10.

issue?).<br></blockquote></blockquote><br><blockquote><br></blockquote><br><blockquote><blockquote><br></blockquote></blockquote><br><blockquote><br></blockquote><br><blockquote><blockquote>Best
