I spent hours searching online for a fix to this issue. I’m glad I came across this post and found a solution that fixed it. Thanks T.McGuire for providing the answer.
I used phpMyAdmin and did a search for gad_oauth_token which resulted in one entry. I deleted it.
I then logged into Analytics and then hit the plugin settings page and was able to re-authenticate with analytics.
I just got the warning myself from WrodFence.
File contains suspected malware URL: /home/content/31/5773431/html/wp-content/plugins/si-contact-form/languages/si-contact-form-sq_AL.po
Something is up. What should be done? Delete the file/plugin or Ignore it?
