I’m using only your plugin for SMTP.
I desactivated others plugins but they are not linked to SMTP.
When I tested again your plugin, without using my plugin, directly after the step 3 of your plugin, I got the same error.
Did you test it on Localhost ?
I remember it was as soon as the first payment did.
I can do a screenshot but I cannot send it by ww.wp.xz.cn.
Maybe give me an email to send you it.
Best regards.
Thank you !
I did this modification (because it was an emergency) and I will update the plugin only where there will be these changes. Can you prevent me please ?
