PHP configuration limitations

If you hit technical issues with the module, you are often redirected here.

The module Information tab includes PHP Info:

Click PHP Info.

Look for these common limits required for the module to work properly:

• memory_limit
• max_input_vars
• max_execution_time

memory_limit: at least 256M (more if you have a large catalog, e.g. > 10,000 products).

max_input_vars: at least 10000 (more if you have many categories, e.g. > 1,000).

max_execution_time: at least 300 (up to ~10,000 products; raise further if needed).

If the Suhosin extension is enabled (search “Suhosin” in phpinfo), also check:

• suhosin.request.max_vars
• suhosin.post.max_vars

These must be at least 10000 (higher for large category trees).

After the host increases them, PHP Info should show values such as:

• memory_limit → 256M (or more)
• max_input_vars → 10000 (or more)
• max_execution_time → 300 (or more)

Under FastCGI, some php.ini settings may be ignored — see FastCGI CDiscount.

If you cannot change these values yourself, ask your hosting provider to raise them.

Do not put a php.ini or .htaccess inside the module folder — it will not work.
