SUJET :

I get an error message:
/home/customer/www/adkins.ws/public_html/app/Statement.php:85 SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '3453099916-3453099916-Expanse, a Palo Alto Networks company, sea' for key 'wt_site_access_rule_ix1' #0 /app/Statement.php:85 PDOException("SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '3453099916-3453099916-Expanse, a Palo Alto Networks company, sea' for key 'wt_site_access_rule_ix1'") #1 /includes/session.php:334 execute([array]) #2 /index.php:31 require('/home/customer/www/adkins.ws/p…')
No significant recent changes in past month or so.
If I try a "back door" approach to access my control panel, I can log on & access my pages, but it appears the index.php may be corrupted in some way.
Suggestions?

I fixed the problem by restoring the index.php backup from yesterday, but I still wonder about HOW the error occurred, and what the heck is "Expanse, a Palo Alto Networks company?"

This will be a robot/crawler visiting your site with a strange user-agent string.

Possibly one that is longer than 255 characters, which would cause this error.

Nothing wrong with your code/site.

You might want to review/cleanup the user-agent-rules settings in your control panel.

Thank you.
