Love it, but problems

Dear mr. Binsaifullah

After a long time (seven months!!!), I finally could find time to test your plugin in an staging area. I loved it, is exactly what I’m looking for, flexible, light and full of options.

But it shows errors that I don’t know how to address, as I’m almost illiterate in code:

warning: Undefined array key “contentBg” in /timeline.php on line 32

warning: Undefined array key “dateNameBg” in /timeline.php on line 75

warning: Undefined array key “dateNameColor” in /timeline.php on line 78

If it helps, I’m working on wordpress 6.4.1 and php 8.1.23.

Do you think you will be able to solve it and update the plugin?

Thank you and best regards!
