Version: 2.4.3
Module: blog-v0.4.1

I have installed the blog module and it works fine until after I post a comment on one of the blog posts. When I try to view the post from the blog holder page I get this error (see below). If I go Firefox > Tools > Clear Recent History > Clear Now I then am able to view the comments again until after the next comment is posted.

Your help is appreciated.

I think I worked this out:

in the php.ini file magic quotes needs to be off. My Mamp installation had them 'On'

magic_quotes_gpc = Off

Correct me if I`m wrong.

Cheers,
David

Good to hear disabling magic_quotes_gpc fixed it. I've added a note to the server requirements.

Thanks

Thanks for posting your solution, could have been stuck on this problem for ages... Cheers!

Helped me a lot too, thanks! On my shared hosting setup I added a php.ini file in to the Sapphire directory which contained the one line 'magic_quotes_gpc = Off' and everything seems to be working now. Cheers

Thanks for this thread. I also suddenly had an error message Form::loadDataFrom() not passed an array or an object on any page with page comments enabled. Clearing the browser cookies or using another browser solved it until I posted the next comment. The issue must have been the commenter name that's stored in a cookie.

As mentioned above magic_quotes_gpc = Off fixes the problem.

magic_quotes_gpc was turned on accidentally because I made a mistake in another part of the php.ini file (I accidentally added a character into the php.ini file where it shouldn't be) and magic_quotes_gpc defaulted to "On", even though in the ini file it was set to "Off".

Just in case anyone else has the same problem.

magic_quotes_gpc is deprecated as of PHP 5.3.0, so it should be safe to get rid of it.

This also reminds me that I should make a backup of my php.ini before I make some changes...
