Hi @Lluis Torns
The issue is not caused because of incompatibility between MultiVendorX and WPML . We have tested the flow keeping MultiVendorX and MultiVendorX Pro deactivated . The error is still coming even when MultiVendorX and MultiVendorX Pro is deactivated. The issue caused because of the incompatibility between the auction plugin and WPML.
