Error and missing text/attachments after upgrade

Just upgraded from 3.0.19 to 3.0.20 and I'm now getting serious problems. Attachments and any text from articles has now disappeared and there's an error line at the top of the screen:

Code:

Warning: preg_replace_callback() [function.preg-replace-callback]: Modifier /e cannot be used with replacement callback in [path]/vault/class/bbcode/obfuscate.php on line 104

The errors seem to occur in any articles where I'm using templates. It also throws up this error on a few different lines...

Code:

Warning: preg_replace() [function.preg-replace]: Parameter mismatch, pattern is a string while replacement is an array in [path]/vault/class/bbcode/template.php on line 547

We get this when the [TEMPLATE] tag is used on 3.0.20r1

Code:

Warning: preg_replace() [function.preg-replace]: Parameter mismatch, pattern is a string while replacement is an array in [path]/vault/class/bbcode/template.php on line 547

We are using PHP 5.3

Do not change the lines as ricktas suggests. The only thing that needs to occur is the /e modifier needs to be removed. It was removed in PHP 5.5, so we had to switch to preg_replace_callback in VaultWiki. It seems we missed one or two instances.

Please follow these instructions if you are running 3.0.20 ONLY and if you are experiencing this issue. Only 3.0.20 contains an updated $obfuscater->undo format which supports these changes. See below...

In vault/class/bbcode/obfuscate.php, find:

Code:

'#\[[^\[]*\]#sUe'

Replace with:

Code:

'#\[[^\[]*\]#sU'

In vault/class/bbcode/template.php, find:

Code:

$name = preg_replace(

Replace with:

Code:

$name = preg_replace_callback(

Find:

Code:

$value = preg_replace(

Replace with:

Code:

$value = preg_replace_callback(

These changes have been folded into the existing 3.0.20 ZIP, so that future downloads don't get this issue. If you are already experiencing this issue, you can apply the changes outlined above in this post, or you can download 3.0.20 again and simply replace the files on your server.

Note: You may also need to use AdminCP > VaultWiki > Wiki Maintenance Tools > Clean Article Post Cache in order to apply the fix to some articles that were affected.
