Hi Andrew,
The same error persists despite that I have installed php-mbstring and regenerated the builtin mapping table. It won't go away :(.
Best,
David

That's a different issue. This problem is that you don't have the mbstring extension installed in PHP, but you need it! If you install the php-mbstring package and try again, that will deal with that issue.
If you then get the earlier error again, here's something that may well fix it: go into the admin control panel, to the mapping tables option, and regenerate the built-in mapping tables.

Andrew.

Hi, Andrew,
Yes, I did. I changed this setting at managing annotation but it remains ineffective in the CQP syntax mode. I got the following error prompt:

Hi, Andrew,
Thanks for the help. I looked into the error log and it appears to be some variable type delcaration problem to me as I compared the "query-lib.php" file with its early 3.2.43 version and found you reengineered the code a bit and had all the variable type declaration (e.g. string, bool) removed. Could this be the cause of problem? I pasted the error below for your reference:

Hi David,
in case of a blank screen, almost certainly there is an error, but it has been printed to your server log instead of to the browser.
there is a PHP ini setting you can adjust for this -- search for "error" in php.ini . or have a look at your log file -- if you are using Apache it will be something like /var/log/apache2/error.log
best
Andrew.

Subject: [CWB] CQPweb does not return results but blank page
Dear All,
I recently installed CWB and CQPweb on a Ubuntu desktop for demo purpose. 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. My corpus was indexed with an earlier version of CWB (should this be an issue?).
Best wishes,
David

Hi David,
Based on this error message, I believe the problem is that you have declared a tertiary annotation, but not specified a mapping table, in this corpus.
To test this, try doing a query in "CQP syntax" mode. If I'm correct, it will work fine.
best
Andrew.
PS. changing from weakly typed to strongly typed function parameters and return values was one of the big changes made in v 3.3.0 . I am reasonably certain the bugs from that changeover are pretty well shaken out.
