If you are experiencing problems with the payment module, there are a couple of things you can try yourself to solve the problem:
1. Update to the latest version of the ePay module.
2. Change the visual theme on your shop to one for the standard WooCommerce themes. Unfortunately, some visual themes are conflicting with our payment module, so please try a standard theme.
3. Deactivate all other installed plugins/modules. Most of the support received for WooCommerce is caused by other plugins conflicting with the functionality of our payment module. Try deactivating other plugins, either all at once, or one by one to find the plugin causing the problem. Please refer to the section "Incompatible plugins" further below, for a list of plugins known to cause problems.
Please contact us regarding specific plugins that cause problems with our payment module, so we can work on improving compatibility with those plugins.
To open different payment windows (with, for instance, different logos) from your shops/domains, use the setting Window ID to govern which payment window to open from the relevant domain.
