Reply To: AJAX import error. Try to disable all external plugins and run the import again.

Hello,

Sorry, this is not possible to connect you with these.

They may be caused by low PHP configuration limits. In this case, you need to increase some values. You can do this on your own or contact your hosting provider with the following requirements:

memory_limit 128M
post_max_size 64M
upload_max_filesize 64M
max_execution_time 180
max_input_vars 10000

Best Regards.
