Problem when display modified date

I guess i’ll double check this, thanks for your feedback

Everything seems to work fine on my config. see this screen capture : https://cloudup.com/cMEmvQlU-RI

In general settings, what are the values of the following settings ?
– Timezone
– Date Format
– Time Format

Yes I saw your video and screen capture. That’s weird in my case.

Timzone : Montreal
Date format : JJ MMM AAAA
Time format : HH h MM min

Seems to me you’re not using correct values there.. See this screencapture with your values : https://cloudup.com/ctnmG-M9XUW

I advised you to have a look at this page https://codex.www.ads-software.com/Formatting_Date_and_Time

Or to use the options provided by WordPress

OK I’m sorry, I translated that to be understood here. I thought that you understand that those format are standard.

As you see, nothing specific in this case.

i’ll wait for your tests without all plugins…
