Hello,

I just logged in to see about running an update to a module; whilst doing so I cleared the cache and then noticed the following warning come up? Any ideas what I should do please?

Warning: Cannot modify header information - headers already sent by (output started at /home/c27ictm/public_html/www.riveroflifelymington.org/concrete/core/controllers/single_pages/upgrade.php:6) in /home/c27ictm/public_html/www.riveroflifelymington.org/concrete/core/libraries/view.php on line 955

Hello again,
I looked at that location and cannot see a white space after the close of the php tag. I am perplexed by the error as the site has been working fine for a year!

Thanks for any help given.

Hello Andrew,

That error popped up yesterday after I ran a back-up and then the CRON jobs. I was thinking of upgrading to the latest version of C5 but am now hesitant of doing this.

So the error was showing in a box at the top of the Administrator screen which I copied and posted here yesterday and today... no error at all shows up, and yes the site is working fine!? Really not sure what is going on. I did look at the two locations mentioned in the error but couldn't see any thing wrong.

Hey Ho!

Lets see what happens....

Thank you for your help and advice.
