Can’t login to admin panel

strange issue. You should delete /wp-content/plugins/wp-fastest-cache/ folder and the rules of WPFC from htaccess.

Thank you Emre.
I originally tried renaming the WPFC folder but it did not help.
I restored the folder name then edited the .htaccess file (to remove the WPFC code) and it eventually solved the issue.
I then uninstalled WPFC and the admin access went back to normal.
Two questions:
1) Does WPFC change anything inside the #BEGIN WordPress – #END WordPress block of .htaccess? I.e. are the plugin’s code changes for this file only within its own blocks?
2) When WPFC is uninstalled, does it restore the original .htaccess code?
Thank you,

No.

Yes.

Hi,
I also think the problem can be in the .htaccess file. If it’s generated automatically by WordPress and you haven’t edited it, that may be the problem.
Here is how it should looks like:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
	# WP Maximum Execution Time Exceeded
	<IfModule mod_php5.c>
	
    php_value upload_max_filesize 1024M
	php_value post_max_size 2048M
	php_value max_input_time 3000

	php_value max_execution_time 3000

	</IfModule>

Hope that will help!
