Дмитрий, вот какое сообщение я получил.

Можете попробовать поставить копию чистого Moodle 2.4 и воспроизвести ситуацию, посмотреть
в чем проблема? Похоже дело в вашем коде...

Hello,

I have a Moodle site that was originally running Moodle 2.3 with this:
https://oasychev-moodle-plugins.googlecode.com/files/preg-question.zip

I upgraded to Moodle 2.4 and switched to this:
https://oasychev-moodle-plugins.googlecode.com/files/preg_231_release.zip

which worked just fine, and the site is running fine and the regular expression questions
are working fine.

However, creating a new moodle site with Moodle 2.4 and preg_231_release, during the
web-based installation process when it's installing the plugins (right after you confirm
the moodle requirements are met OK), it errors out with this:
---------------------------
Error reading from database

More information about this error <<== links to http://docs.moodle.org/24/en/error/moodle/dmlreadexception

It is usually not possible to recover from errors triggered during installation, you
may need to create a new database or use a different database prefix if you want to
retry the installation.
Debug info: Table 'moodle.mdl_block_formal_langs' doesn't exist
SELECT * FROM mdl_block_formal_langs WHERE visible = ?
[array (
0 => '1',
)]
Error code: dmlreadexception

---------------------------

The problem is the mdl_blocks_formal_langs table isn't created in the database.

I see there's a blocks/formal_langs/db/install.xml file that defines that table that
I guess Moodle is supposed to use to create it.  I compared it to an install.xml from
another plugin and the format looks fine.  I tried changing some things in the XMLDB
PATH at the top, which didn't help:
PATH="blocks/formal_langs/db" rather than PATH="question/type/correctwriting/db" which
certainly didn't look right, and xsi:noNamespaceSchemaLocation="../../../lib/xmldb/xmldb.xsd"
rather than xsi:noNamespaceSchemaLocation="../../../../lib/xmldb/xmldb.xsd" to match
what another plugin had.

I am stumped.  Do you have any ideas?
