Just to furnish more information, initially I thought it was a RAM issue (256MB) so I tried a new installation on a 512MB VPS from the same provider, Atlantic.net. The virtualisation techique is KVM and should not experience the OpenVZ RAM issues.
However, the same issue persists. It’s a fresh installation of WordPress on top of Virtualmin.
The strange thing is that I tried the same configuration from another VPS provider, DigitalOcean, and everything zips just fine.
However, Ubuntu is configured a little differently between the two providers. Thus, I think some package may be missing on the Ubuntu packages from Atlantic.net.
Thus, my question is: What Linux/Ubuntu packages are required for zipping to work?
Well, I found the problem. I was using a 32-bit image on Atlantic.net and a 64-bit image on DigitalOcean. When I tried a 32-bit image of 14.04 on DigitalOcean I get the same issue as well.
Thus, it seems that UpdraftPlus doesn’t work on 32-bit versions of Ubuntu 14.04? Is there any way to make it work out of the box?
Hi,
Interesting, thank you. What’s logged in the PHP error log at the time that it crashes?
David
Well, it seems to show ‘Abort class-pclzip.php : Missing zlib extensions’ at the top of the page after enabling PHP logging.
Thank you.
That’s interesting. class-pclzip.php doesn’t come into it with binary zip (which just calls /usr/bin/zip) – but it suggests something related. Both, under the hood, likely are linking to a zlib library which you haven’t yet got installed on the system. Though, that’s also a bit puzzling, as WordPress needs some zip functionality to unpack a plugin (unless you installed it manually). Perhaps PHP’s ZipArchive uses something else. Not sure. But anyway, if zlib’s not installed, then you’ll need the UPDRAFTPLUS_NOBINZIP defined, to skip on to trying ZipArchive as the next option.
Best wishes,
David
Thank you.
Now I have narrowed down the problem to the lack of ‘gzopen’ on Ubuntu 14.04 x32.
I followed your instructions in another post and added this into wpconfig:
function gzopen( string $filename , $mode, $use_include_path = 0 ) { return gzopen64($filename, $mode, $use_include_path); }
However, now I’m getting another error:

Any idea what’s wrong?
Hi,
You need to remove the word “string” from the first parameter here:
function gzopen( string $filename , $mode, $use_include_path = 0 ) { return gzopen64($filename, $mode, $use_include_path); }
After you installed Ubuntu 32-bit, did you update it to the latest packages? I believed that the defect in PHP in the initial Ubuntu release (the missing gzopen function) got fixed in an update.
David
Yes, I did run apt-get update, apt-get upgrade and apt-get dist-upgrade immediately after the image was created, but the same issue persists.
I guess for my low memory VPSes I have to use Debian x86 instead. I don’t know if it’s too much trouble for you to add in extra code just to support Ubuntu x86.
Removing string seems to have done the trick though. Thank you!
Hi,
I’d much prefer that Ubuntu were pressured to fix their bug – because this affects multiple PHP projects, not just UpdraftPlus (every PHP project using the gzopen() function): https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1315888
Best wishes,
David
You could point out to them that the upstream PHP bug was finally fixed a few weeks ago – https://bugs.php.net/bug.php?id=53829 – so, they just need to roll in the fix to their PHP build.
David
