Errors post-upgrade

[soj]

Rats, not outta the woods yet. We are unable to upload a large submission. The file size is 6 mb. I can upload smaller files.

I tried increasing the memory limit in php.ini via htaccess:
php_value memory_limit 32M

Still no luck on large files.

Then I tried:

php_value upload_max_filesize 50M

That worked ;-)

However, I turned php errors display back on and got these errors in header. None in the footer.

Thoughts?

Hi Soj,

Are you using Zend optimizer or another similar product? If so, try disabling it and see if that fixes the problem. Some versions optimize code like:

Code: Select all

function &myFunction() {
        $myVar = false;
        return $myVar;
}

into:

Code: Select all

function &myFunction() {
        return false;
}

which looks harmless enough, but in fact contravenes PHP's reference rules, resulting in warnings like the ones you mention.

At any rate, the warnings you mention are irritating but harmless -- if you can't track down what's causing them, just make sure warning messages aren't displayed and OJS will work fine.

Incidentally, what version of PHP are you using?

Zend? Yup!

PHP Version says 4.4.1.

And true, everything works as long as the error msgs are turned off. Thought you'd want to know, tho.
Thanks!

Hi Soj,

Thanks for the info -- the problem here is an incompatibility between PHP 4.4.x and Zend Optimizer 2.5.10. There's a note on this problem at http://loudblog.de/forum/viewtopic.php?pid=1720 and http://bugs.php.net/bug.php?id=34009; I couldn't find anything official. As I mentioned, if you can't upgrade your PHP and/or Optimizer versions, hiding these error messages won't cause any problems.

I tried to install OJS and had similar Only variable references should be returned problems. I'll ask the ISP support to update the Zend optimizer, but in the meantime, I can't figure out how to turn off the warning messages. There doesn't seem to be such a toggle in the [debug] section of Config.inc.php. Help!

[Sherman]

My ISP's support staff suggested putting the following in a file php.ini in the main OJS folder (where index.php and config.inc.php are):

register_globals = on
post_max_size = 20M
memory_limit = 80M
upload_max_filesize = 20M
max_execution_time = 120
expose_php=off

This is for systems where Zend is not turned on by default, and it simply repeats the system defaults (for me) for php. It worked!

I had the same problem with the post-install error messages in the header. Putting "session.auto_start=Off" in my php.ini file solved it.
