Suddenly Errors!

[soj]

Reposted to a new topic. I am suddenly getting a pile of errors. It's pretty much crippled the whole site.

According to my web host, the php version is 4.4.1 on a FreeBSD 4.11-STABLE server. We are using OJS 2.0.2 . Since we have not modified the site at all since launch 3 weeks ago, I suspect something has changed on the server side.

Any thoughts or help would be very welcome indeed!

Hi Soj,

This was probably caused by a PHP upgrade. The most recent releases of OJS 4.x and 5.x have started to complain about reference problems where previous versions just carried on. Try suppressing warning messages -- either change the error_reporting directive in your php.ini configuration file, or use the ini_set function to do the same thing (see http://ca3.php.net/manual/en/function.ini-set.php). These issues have been corrected in the CVS version of OJS and the next release, which is due at the end of the month.

Once the warnings are suppressed, the system should behave normally.

Thanks, Alec! I was afraid of that. Is there any way to turn off the warnings from within the OJS application? Otherwise I'm at the mercy of my hosting provider Level II techs.

Update: Maybe I can change the value via htaccess???

Update2: Yes! I placed the following into an htaccess file and it worked:
php_value display_errors 0

based on:

To change in .htaccess (works if php is used as apache module), add:

php_value php_option_from_list VALUE

To change the value in a php-script do:

<?php
ini_set("php_option_from_list",VALUE);
?>

VALUE is 0 or 1

Also of possible use to others:

Here is the code to view your php.ini file from your browser. Create a new page and paste just these 3 lines of code inside it, and call it phpversion.php or something like that.

<?php
phpinfo();
?>

Alec, if you have an email distribution list for upgrades, please add:
webmaster@ejssm.org

Thanks again!

Hi Soj,

FYI, there's a registration page where you can sign up for security notices and news about OJS. See http://pkp.sfu.ca/ojs/register.

I had the same problems crop up just yesterday (hosting via Dreamhost...still not sure if they did something or what). The other htaccess solution didn't work, but thanks to help from jeremy h. putting the following in a .htaccess file did the trick:

php_flag display_errors off

I've been searching for a solution to this problem of php 4.4 attacking adodb for nearly 10 days now. Finally found it in the .htaccess file solution. Thanks for that brilliant bit of coding.

Thanks a bunch.

P.S. I registered ESPECIALLY to post here and thank you guys. Now that i'm here though, it seems to be an interesting forum. I'll wander around a bit more. Thanks again.
