Hi again,
Thank you for the info. The problem occured when I was upadting. The is no option to do it again ( updating). What I tried to do was to uninstall the theme and install it again, what is impossible as error info appears again.
I will do what I can do with my poor informatic skills.
If I can not solve it, I write you again if you do not mind.
Thank you again for the fast help.
PS
(Zakra is the best theme I have worked with)
Best wishes, kris100
