To resolve the issue, follow this diagnostic sequence:

Double-click the values and verify that the directories listed exactly match your real-world folder structures. Correct any typos or outdated drive letters.

# Set correct ownership chown www-data:www-data /var/www/html/config/tecdoc.cfg.php # Set secure yet readable permissions chmod 644 /var/www/html/config/tecdoc.cfg.php Use code with caution. For Windows Environments: Right-click the TecDoc data folder and select . Navigate to the Security tab.

Right-click the configuration file and select .

If you recently edited the file, look for syntax errors.

<BDFConfiguration> <DataPaths> <string> C: Files/tecdoc2020q1 Data </string> <string> Media </string> </DataPaths> </BDFConfiguration>

TecDoc relies on specific configuration files—usually named TECDOC.INI , TAF.INI , or similar configuration variants—depending on your version (DVD/Offline vs. Web/Catalog integration).

Check the column. If it is blank, right-click the service and select Start .

If path corrections and permission updates fail to resolve the issue, a clean reinstall will reset the configuration files back to a working baseline.
