Thanks nietdanNL for your help.
I deleted all the tables in my sql database.
Installation returns first “Fatal error: mysql_num_fields(): supplied argument is not a valid MySQL result resource in /mnt/113/sdb/4/4/wernerb/wp-includes/wp-db.php on line 728”.
WP asks then for repairing and returns the following error message :
“The wp_users table is okay. The wp_users table is already optimized.
The wp_usermeta table is not okay. It is reporting the following error: Table ‘wernerb.wp_usermeta’ doesn’t exist. WordPress will attempt to repair this table…
Failed to repair the wp_usermeta table. Error: Table ‘wernerb.wp_usermeta’ doesn’t exist [snip]”
I can see in mysql that WP has created 10 tables, but not the wp_usermeta table ???
Thanks, werner
