Hi evergreenframedart
Have you got FTP access to the website? If so, I would rename the following directory:
/wp-content/plugins/portfolio-slideshow/
to
/wp-content/plugins/portfolio-slideshowx/
That should disable the plugin and let you log back in. If it doesn’t then try using the Forgot Password option when logging in.
If that doesn’t work ideally you’ll need access to the database as there’s a way to amend the password…
1) Access phpMyAdmin
2) Click on the database
3) Find wp_users and click on it
4) Against your login click Edit
5) In user_pass switch to MD5
6) Amend the encrypted box to whatever password you want to use
7) Click the Go button
You should now be able to login using your new password.
Hope you get in!
