I can not log in my dashboard please help

can u give some more information that how did u install the plugin. and if there are other plugins also enabled on ur site.

or may be just check the code in the files that is being shown in the error.

Please don’t shout/type in capitals.

FTP into your website and rename/delete the “wassup” plugin.

Otherwise rename your plugins folder from “plugins” to “plugins-temp”.

Confirm you can login to WordPress then rename your plugins back to the default. You will then need to manually reactivate each plugin. Suggest you remove the plugin causing the error or find a solution so that it works.

Yep, please don’t use all caps.

Now if it’s a plugin, just as threestyler wrote, using FTP or whatever file management tools your host has provided you rename wp-content/plugins to wp-content/plugins-temp`.

Or if you can modify your database, you can deactivate all of your plugins that way.

Sorry for using capital letter.You are saying edit plugins.But Ican not Log in my wordpress site.you can see here is my site address.

https://www.melody24.com/wp-admin/

sothat how can i log in my site & edit this plugins.

Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin.

– re-uploading all files & folders – except the wp-content folder – from a fresh download of your current version of WordPress.

You site does not exist. Please get you host tech support to help you restore your site.

I have allready contact with my site provider.He wants 30$ for repair the site & themes.

That seems reasonable. I’d suggest that you take him up on his offer.
