Hy Tom,
Thansk for your answer.
Now I’m sure that the last version of WP isn’t the problem because in other WP that I’ve running with GP all is ok.
I publish a screenshoot of the problem in a hide page: http://eldesvandelasletras.com/costumize-options-do-not-load/
When I go to “costumize” I can’t see the options that I need to change the header, the layout, colour, blog options, widget options… that normally are in the left column.
I tried deactivating the plugins, but I do’nt found any incompatibility.
I deleted and reinstal·let the theme… nothing.
I tried too with “FreeLAncer” theme and the situation it’s the same.
I tried with other themes and all runs perfect 🙁
Any suggestion?
Thansks again.
