Most installation issues are caused by server configuration rather than the plugin itself. Here are the most common problems and their solutions.
White Screen / HTTP 500 After Activation
Cause: PHP memory exhaustion or a fatal error during the installer.
Solution:
- 1
Enable WordPress debug mode in
wp-config.php:define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); - 2
Check
wp-content/debug.logfor the specific error. - 3
If the error is Allowed memory size exhausted, increase
memory_limitto at least 256 MB.
Database Tables Not Created
Cause: The WordPress database user lacks CREATE TABLE privileges, or the installer ran in an environment that interrupted execution.
Solution:
- Check that your WordPress database user has full privileges (or at minimum: SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER).
- Deactivate and re-activate the plugin to re-run the installer.
- If re-activation fails, navigate to Influenzic → Tools → Run Database Migration to trigger table creation manually.
inzc_ (e.g. wp_inzc_campaigns). If they don’t exist, the installer did not complete.
Frontend Pages Return 404
Cause: WordPress permalink (rewrite) rules are stale.
Solution: In WordPress admin, go to Settings → Permalinks and click Save Changes without changing anything. This flushes the rewrite rules.
Plugin Conflict
Symptoms: Layout broken, JS errors in the browser console, unexpected redirects.
Diagnosis:
- 1
Deactivate all other plugins except Influenzic.
- 2
Test if the issue persists. If it resolves, re-activate plugins one by one to identify the conflict.
- 3
Common conflicts: page builders (Elementor, Divi), security plugins (Wordfence, iThemes Security), caching plugins loading outdated assets.
Upload Errors (ZIP Too Large)
Cause: Server upload_max_filesize or post_max_size is too small.
Solution: Ask your host to increase these limits, or edit php.ini / .htaccess:
# In .htaccess (Apache)
php_value upload_max_filesize 64M
php_value post_max_size 64M
