At last after one year of hard work, many changes and upgrades, a lot of articles, galleries and improvements, I made a mistake and now my WP website crashed... I can't open a WP admin, can't reached the main dashboard and can't repair...
The mistake ruined my website was: on General setting I wrote a wrong website address/location. I did not want to reinstall WP because it means the one year work will go away...
Maybe somebody can tell the simply way how to repair some .php or other files... I can access all my files through FTP and could change any info on any file -- if I know what and where to change...
Sorry my bad English and a lot of thanks to everyone who will try to help me!...
