So many errors after upgrade

[Sven]

Hello,

we upgraded the events calendar and the events tickets to pro. After installing the Add-Ons and activating the license, nothing works. When we want to edit an event, there is nothing loaded. Just a blank page under the events calendar. Also we get an http 500 error after installing and activating the tickets pro Add-On… This error is gone, after deinstalling tickets pro.

We really need help to get this working!

Best regards

Hi Sven

I’m really sorry to hear that and would love to hear more so we can figure out some sort of solution.

Unfortunately, for some reason, we weren’t able to collect your system information. Is that something you could share by private reply? I’m particularly keen to learn which versions you updated from.

I wonder also if you could enable WP_DEBUG (even if temporarily) and see if you can capture any error messages that might inform our picture of what’s going wrong.

Thanks so much!

Can you try increasing the amount of memory available to PHP?

codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP

Something like define( ‘WP_MAX_MEMORY_LIMIT’, ‘256M’ ); could be worth a shot in the first instance.

[Sven]

I set the WP_MAX_MEMORY_LIMIT to 256M but it throws the same error as before. If i log out from wordpress, i cant get back in because of the HTTP ERROR 500. Deleting the Tickets Pro Plugin resolves this issue. Even without the Tickets Pro, the part where the configuration for my event should be is empty (shown on the screenshot given to you before). It worked so good without the pro add-ons, but the free solutions doesn’t suits us at all…

[Barry]

So very odd.

OK, can we take a step back and review the initial troubleshooting steps? I do realize you indicated having deactivated all other plugins except for ours and appreciate you taking the time to do that. Would it be possible for you to repeat that process and additionally switch from your current theme to a default theme such as Twenty Seventeen?

Alternatively, would you be able to create a fresh WordPress installation in a subdirectory (ie example.com/test-wp) and start by installing only our plugins and see if you can replicate the problem there? Assuming you can’t, add WooCommerce and test again, and repeat until the test site has the same plugins, theme and configuration as the live site.

I know this seems like a lot of work, but this is an unusual problem and we aren’t seeing comparable reports from other users – making me think something specific to your site is behind this issue.

[Sven]

Unfortunately, we can’t switch back to a different theme on this site, because it is already heavy in use. We also don’t have access directly to the hosting server (to change settings there e.g. php.ini) – So what i did was setting up the site on a different server with the theme and all the plugins. Works perfectly… So i come to the conclusion, that there is a problem with the server. So one difference between these two servers, is mine has PHP 7 and that from the hosting provider 5.3.3. maybe there is an issue with that?

In that case, i need to contact the hosting provider.

[Barry]

OK, an interesting find.

I do tend to think that the PHP version itself probably isn’t to blame here, but it does sound like something unique to your live site is behind the problem.

If you want to try and seek assistance from your host that could definitely be worth a shot; it does also occur that using Duplicator or a similar tool to make an exact replicate of your live site (data, configuration, everything) on your test site could tell us if that is the case.

[Sven]

Hey Barry,

i duplicated the site, but still no error in sight. Everything works perfectly. So i checked the error log from our hosting provider and it says:

- mod_fcgid: can't apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper
- mod_fcgid: stderr: PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 61441 bytes)

So i guess not enough ram and FcgidMaxProcesses is set too low?

It does rather sound like this is an environmental issue that the host may be best placed to solve, yes.

[Sven]

Yes, after contacting my hosting provider, we could resolve this issue!

So for everyone who encounters the same problem:

• Make sure your PHP has a high enough memory limit to run the events ticket pro plugin (That was the one messing everything up). You can change the memory limit in your php.ini file (search for memory_limit) and set it to 160M at least.
• Increase your FcgidMaxProcesses in the fcgid.conf file after you increased your memory_limit! After that, restart Apache
• If you don’t have access to these files, ask your hosting provider to do it!

Thank you Barry for your support! I mark this issue as resolved!

[Barry]

Thanks for confirming Sven and for sharing those details: should be useful for others in a similar boat ?
