<div dir="ltr">Dear Andrew<div><br></div><div>We are experiencing errors with our CQPweb installation on Ubuntu 14.04 running on apache. This seems to have cropped up suddenly (it wasn't happening before). The error occurs in one of two places:</div><div><br></div><div>1. When trying to run a concordance; OR</div><div>2. After running a concordance, when seeking to expand one of the results, building a frequency table, etc.</div><div><br></div><div>Since the error occurred, I have tried to reset the saved_queries table (since the error seems to involve a query handle). I have also upgraded to the latest version of CQPweb from the subversion repo, and run the db setup php script, followed by a restart of the mysql and apache services. The problem, however, persists. </div><div><br></div><div>It seems to be coming from a CQP error. I reproduce the error message and stacktrace below.</div><div><br></div><div>Thanks in advance for any advice</div><div>albert</div><div><br></div><div><div>**** CQP ERROR ****</div><div>ERROR: File
