@tkembo Which version are you using?

[tkembo]

I'm on Version 1.4.7

[ole1986]

Can you please check your database table wp_options for the option_name timezone_string and let me know the value?

[tkembo]

there is no timezone_string in the table. There is only time_format and date_format. Could that be the reason?

[ole1986]

Yes, this is the reason. It does not check for any default value. So timezone "" is invalid.
As a workaround you can save a timezone from the wordpress settings page matching one of those in the list

Alternatively I am going to patch this in the next version 1.5.0

[tkembo]

thank you. this was very helpful.
Out of interest, when can we expect version 1.5.0 to come out?

[ole1986]

Since v1.5.0 is only a compatibility update to wp-ispconfig3 it may happen very soon
