Recently, some of our users have encountered an error code where the vufind db error extension was not found. There are many factors causing this problem. Let’s take a look below.

If VuFind is not working as expected, there are several things you can do to get more information on errors.
Check Logs For Errors
Change Development Mode
Apache configuration VuFind comes with an environment variable called VUFIND_ENV, which experts say tells the software whether it is in development or production in the associated environment. By default, my is set to production, which starts performance-oriented caching and disables highlighted error messages for added security. If you pass this parameter to community mode (by editing $ VUFIND_LOCAL_DIR / httpd-vufind.conf, commenting out the required VUFIND_ENV line, and restarting Apache), cache problems will in most cases be automatically cleared and any screen errors will occur. displayed normally for debugging purposes.
When in doubt, clear the contents of $ VUFIND_LOCAL_DIR / cache – this can fix some common problems such as changes to word files that are notfight right away.
Check Authorization – Security Settings
If Apache is not allowed to read or write certain web pages (especially the cache), VuFind may have problems. The $ VUFIND_LOCAL_DIR / cache directory (and several of its subdirectories besides cli) must be writable by a user using Apache (often called www-data or apache, depending on the operating system). The $ VUFIND_LOCAL_DIR / cache / cli directory (and all coverage subdirectories) often needs to be writable by running the user’s command line utilities. Also make sure SELinux does not interfere with VuFind see; See our own Fedora Installation Guide for more information on SELinux.
Activate Debug Mode
If you need more information about what vufind does, you can set any debug setting in the [System] section of your Found config.ini file (usually $ VUFIND_LOCAL_DIR / config / vufind / config.ini) to true. This leads to debugging as the messages are contained in most of the HTML generated by VuFind. In many cases, this reveals additional useful For information, be aware that in many cases debug messages are nearly impossible to read and may interfere with some VuFind AJAX features. If you have these problems, try the next section….
Debug On The Fly
You can also enable debug mode using the URL parameter as if you had configured the appropriate permissions. If you add “debug = true” directly to the parameter at the end of any VuFind- url (with the appropriate delimiter of course? Or otherwise & -), the debug function will be enabled as long as the user has there is an “access.DebugMode” authorization, which is authorized through the authorization system . This advantage has been broken in several versions of VuFind; See VUFIND-1382 for details on enthusiastic releases and fixes.
In case of illness, when you need to closely examine the behavior of your code, consider using the PHP Xdebug extension for full code-level debugging functionality. Step – Code includes, checkIt picks up variable values, etc. Some IDEs support Xdebug and Google search for “Xdebug”, and the application you choose should provide advanced instructions on how to watch TV. If you’ve never used an IDE before, you can find paid open source options on the dedicated Recommended Tools page.
If clients do not see errors on the screen, there is a good chance that they are indeed caught by the Apache error log (often found in /var/log/apache2/error.log, /var/log/httpd/error.log). , also called in a similar way). Checking that the log is stopped (or using tail -f to keep track of it) can reveal useful information.
Some operating systems use PHP-FPM to run PHP, and the PHP-FPM error log is another area to check in this case. It is usually listed in /var/log/php-fpm/www-error.log (or something similar).
If quick debugging of root issues on the screen suits or doesn’t suit your end requirements, you can also enable casea VuFind torus that is controlled in the [Logging] config.ini page. This gives each person the ability to control the type of voicemail messages that are recorded, the level of granularity in which they are named, and where they are sent: their log file, data source table, email address, and more. Configuration file comments describe parameters in more detail.
Logging is not only a useful way to fix a known problem, but it is also a good way to detect unknown problems – it is highly recommended that you set up a production system scan and continue if there is activity. Unusual.
