Questions before you start
How does the 7-day free trial work?
Start your subscription in Stripe with a payment method. Your first charge of 3 € per month plus applicable taxes is due after the 7-day free trial. Cancel before the trial ends from your Devman account to avoid any subscription charge. No commitment.
What should I do if I already have caching enabled?
If you already use another full-page cache, disable it on a staging copy before enabling Performance Pro, so you can avoid overlap and compare results. OPcache, browser caching and a CDN can remain enabled, but review their configuration and purging with your hosting provider. Back up your store and check it after the change.
Will it work with my theme?
Performance Pro is designed to work with supported OpenCart versions without depending on a specific theme. Choose the correct package in the installation guide and test custom themes and other extensions on staging before enabling it in your store.
Will my score reach 100?
Results depend on hosting, theme, traffic and external scripts. Reaching 100 is not guaranteed. Performance Pro is designed to reduce load times; the improvement depends on your installation and is shown by your measurements.
What happens if I stop paying?
Local acceleration continues until the signed end date of your trial or paid period. After that, Performance Pro stops accelerating your store; the store keeps working normally.
Which languages are available?
English (the default), Spanish, German, Russian, Ukrainian, Portuguese (Portugal), French and Italian.
