Plugin giving me 503 Service Unavailable Error

hi! I’m sorry to hear that – we have not had any reports of this. 503 usually means the server’s capacity is reached (it could be the proverbial straw that breaks the camels back). Can you try to remove the plugin entirely and reinstall? You could also contact your host and ask them whether they can tell you more about the 503 error. If you are on cheap hosting you may simply have reached your servers limits.

Let us know what you find!

Hi Ewout,

I have plenty of resources left on my server, the error appears as soon as I activate the plugin before anything else was activated. I tried reinstalling and now starting to get the 500 error. I see there are others in the forum starting to get the same error. Hope you guys resolve it soon, because I really cannot find a better invoice plugin than this!
Cheers

Hi! A 500 error is a cover up for another error and could be anything (the two reported 500 error threads currently open are unrelated and 2.1.3 is currently used on 20.000 sites so I think this is not related directly to the update). Check this sticky post and let me know what you find!

We always do our best to resolve these kind of issues as soon as we can, but we need as much information as possible when we’re unable to reproduce the issue so we can track down the root cause. Let me know what you find!

Hi Ewout,

I reinstalled it again and it worked! I’m not sure why. The debug mode didn’t show anything unusual.
Thanks

Strange… glad to hear it’s all working now – let me know if the issues come back though!

Hi Ewout, please see error log below. Is this to do with my theme? Thanks

Hi! These are all different errors, but from first sight it doesn’t look like they are directly related to PDF invoices:

PHP Fatal error: Uncaught Error: Call to undefined function wc_print_notices()
Is indeed from your theme (flatsome), which appears to be crashing when your site is in maintenance mode.

PHP Deprecated: Non-static method BE_Multiple_Packages::generate_packages() should not be called statically
Appears to be coming from a plugin “Multiple Packages for WooCommerce”. Nothing serious that crashes your site, but you could still report it because it will break in future PHP versions

PHP Fatal error: Allowed memory size of 134217728 bytes exhausted
Could be anything… 134217728 bytes = 128M which is probably your PHP or physical server limit. The server runs out at wp-includes/formatting.php in a function called untrainlingslashit, but that could be any plugin – as I wrote before, this is probably a ‘straw that breaks the camels back’ type of situation…

Hope that helps!
Ewout

Thanks a lot.
