hello dear friends i have a problem, last night i changed my wordpress theme, but after changing the theme every page got white white instead of opening. i tried to login to admin area, that page was also white. all page go white. i deleted that theme through ftp. i thought that this is not a problem, after deleting theme, default theme will be automatically activated. but problem still exists, default theme is not activated. now how can change my theme. In my opinion default theme always get activate when we often delete currently using theme.
By doing so, your problem must be resolved, but if it still exists then reinstall your wordpress by taking back up of your database to restore your postings.
