Post publishing miss even after installing and activating the Plugin

Hello all,

Today my scheduled posts have stopped getting published even after installing and activating the Missed Scheduled Posts Publisher by WPBeginner plugin. It worked fine yesterday, but not today

I have tried the below in terms of troubleshooting –

• Checked that the timezone is correct in settings > general
• Delete cache using “LiteSpeed Cache” plugin

Please advise what else can be done. Thank you.

Regards.
