Error message after WordPress update: Cannot set max execution time limit

Hi all

After updating to the latest version of WordPress 1 week ago, I first got this error message in the top when I’m in the Control Panel:

“Cannot set max execution time limit due to system policy in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php on line 64 Warning: Cannot modify header information – headers already sent by (output started at /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php:64) in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-admin/includes/misc.php on line 1198”

It provided another problem after I installed the Force Login Plugin. When “not-logged-in-users” then try accessing my website they don’t get a chance to login, but only this message:

“Warning: set_time_limit(): Cannot set max execution time limit due to system policy in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php on line 64 Warning: Cannot modify header information – headers already sent by (output started at /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php:64) in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-includes/pluggable.php on line 1251 Warning: Cannot modify header information – headers already sent by (output started at /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php:64) in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-includes/pluggable.php on line 1254”

A couple of days went by and then something changed.
Now the situation has gotten worse, since I now can’t log on to the webpage and therefore can’t enter the control panel.

When I go to the webpage (both on Google Chrome and Safari) I see our normal starting page but with this error message written in the top:

“Warning: set_time_limit(): Cannot set max execution time limit due to system policy in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php on line 64”

When I try to log on using Google Chrome, I get the error message nr 2 (Warning…)

When I try to log on using Safari, it says there has been an error and that cookies have been blocked because of unexpected poutput and gives me the option to try logging on again, and present following in the top of the page:

“Warning: set_time_limit(): Cannot set max execution time limit due to system policy in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php on line 64 Warning: Cannot modify header information – headers already sent by (output started at /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php:64) in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-login.php on line 447 Warning: Cannot modify header information – headers already sent by (output started at /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php:64) in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-login.php on line 462 Warning: Cannot modify header information – headers already sent by (output started at /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php:64) in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-includes/pluggable.php on line 928 Warning: Cannot modify header information – headers already sent by (output started at /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php:64) in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-includes/pluggable.php on line 929 Warning: Cannot modify header information – headers already sent by (output started at /customers/2/2/5/soenderborggade.dk/httpd.www/wp-content/plugins/subscribe2/subscribe2.php:64) in /customers/2/2/5/soenderborggade.dk/httpd.www/wp-includes/pluggable.php on line 930”

Does anybody know what to do to get my homepage back up running?

I have backups of the webpage from the programme BackWPup, but it seems like I would need to buy their software to use a backup?

The page I need help with: [log in to see the link]
