Weird.. Have you checked the database on your own?
- Are you in the administrator group? Get your user id from the
{tableprefix}_userstable and search for the coresponding meta key{tableprefix}_user_levelfor your user id inside the{tableprefix}_usermetatable. The value should be set to10. - Do you have migrated the database from another wordpress installation? If it’s really an autoincrement problem, you could use a db tool (e.g. phpMyAdmin) to set the
AUTO_INCREMENTattribute. I haven’t tested this, so please make a database backup before and use a testsystem. Open your database, select a table (e.g.{tableprefix}_posts), click theStructuretab and edit theIDcolumn. There you can enable/disable theAUTO_INCREMENTattribute for this column. Another approach is to export the hole database with theAdd AUTO_INCREMENT valueselected, delete and re-import the database.
