 * This is a new website. I uploaded Updrafts plugin to make a backup. It sends 
   the file to Dropbox. When the backup ran, I got this error:
 * PHP event: code E_WARNING: unserialize(): Extra data starting at offset 2993 
   of 3008 bytes (line 193, wp-content/plugins/updraftplus/includes/Dropbox2/OAuth/
   Storage/WordPress.php) (May 04 22:26:44)
 * This site is operating on php8.3. Current WordPress.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-php-event-code-e_warning-unserialize%2F%3Foutput_format%3Dmd&locale=en_US)
