PHP upgrade breaks version 1.9.12+

PHP upgrade breaks version 1.9.12+

Upgraded from php 5.2.17 to 5.3.15 on a fully functional moodle install version 1.9.12+.

Nothing changed on my moodle install or configuration.

I have tried everything I can find within these moodle forums.

Site Admin:

Server --> Environment shows all OK

Errors I get are that within an existing course, when one selects "link to file" option the file does not link and the error is:

"No valid arguments supplied or incorrect server configuration"

File is not found - have verified that file is on server. Also, when I select the "Update resource" option and "Choose or upload file" I can see the target file, however there is not an "Choose" link available.

Moodle is clearly not resolving the path during selected file operations.

PHP info:

Hmmmm.... I'm not saying this isn't related to the PHP upgrade but I'm sceptical that it has anything to do with the version change per se.

A bit more information wouldn't go amiss... what sort of system is this (operating system)? How was the upgrade done? Have you run Moodle with Debugging switched on? Have you checked your web server error log?

Also, was php.ini changed as part of the upgrade. If so, what was changed? If you still have the old version do a diff and see if anything jumps out at you.

Thanks for replying,

As given above it a Linux server running Apache with Cpanel  WHM Centos.

I did the php upgrade from Cpanel.

No server related errors in the logs.

With debug on I get :

Warning: preg_replace() [function.preg-replace]: Compilation failed:
unknown option bit(s) set at offset -1 in
/home/phost/public_html/lib/moodlelib.php on line 465

Searching the interent this COULD to be related to the PCRE extension bug not being compiled with UTC-8.

That's the one. Seen it before. They've build it using a non-utf8 PCRE library.

Should be easy enough to fix, but means recompiling the PCRE library and then PHP.

Seeing as you mention Cpanel, I suspect you will have to complain to your hosting company.

Ok, recompiling the PCRE library with utf8 support fixed it.

For the other folks arriving at this thread, here's the steps on a Linux box:

I already had the source file on my server.

cd /var/cpanel/perl/easy/Cpanel/Easy/OptLib

tar xvzf  pcre.pm.tar.gz

cd  pcre-8.21

./configure --enable-utf8 --enable-unicode-properties

Then, via cPanel rebuild using EasyApache

 

Thanks Howard...
