Upgrading to 4.1.1 or 4.1.2 crashes my site

[Camilla]

Tried a few weeks ago to upgrade from 4.1 to 4.1.1 and ended up with Error 500 for the site.
Reverted back to 4.1 and all good.
Today I tried again to upgrade to 4.1.2, on my staging server this time, thinking you may have fixed the issues in 4.1.1 and still getting the Error 500. I noticed there were some other users who had experienced similar things.

The test/staging server is http://www.westlingfamily.com/sacc

Please advice what I (or you) might be doing wrong.

Hi. Sorry you’re experiencing this, and thanks for your system information.

Thanks for reaching out to us about this.

There could be quite a few things that would lead to a plugin or theme conflict, and I’m curious about a few things. Would you mind enabling WP_DEBUG and sharing any PHP errors you see while navigating your site’s home page, events page, single-event pages, and any other of your site’s pages relevant to this ticket?

Once you share your WP_DEBUG findings, we may be able to get an idea of any plugin or theme conflicts.

Please enable WP_DEBUG on your site. You’ll need to edit to your site’s wp-config.php file and change this line of code: define('WP_DEBUG', false); to this: define('WP_DEBUG', true);
(or add this line of code if you can’t find mention of ‘WP_DEBUG’ in your wp-config.php file)

If any errors do appear while navigating your site’s pages, please copy and paste them in their entirety into a new ticket reply — along with the URL of where you saw the error(s) — and make sure you set it as a Private reply.

Let us know what you find. 🙂

Thanks for sharing your WP_DEBUG messages.

There were one or more releases since our last interaction. Could you please make sure all your Modern Tribe plugins (and WordPress core) are at their latest versions?

• Downloads / Version Numbers
• TEC Automatic Updates
• or TEC Manual Updates
• WordPress core updates

Once you verify you’re on the latest versions, please test to see if the issue is still happening for you.

Thanks!

Hi Cliff

Sorry, I’m not sure I understand your advice of asking me to upgrade to the latest modern tribe plugins when this is exactly where I’m getting the problem??

Did another test in my test environment upgrading to Event Calendar Pro 4.1.2 and the site crashes with the following message displayed on the screen.

Fatal error: Call to undefined function tribe_get_event_label_singular_lowercase() in /home3/westling/public_html/sacc/wp-content/plugins/events-calendar-pro/src/Tribe/Main.php on line 418

I’m guessing you have The Events Calendar PRO active without having The Events Calendar active, since that’s where tribe_get_event_label_singular_lowercase() is from…

Please activate TEC core/free first, then activate PRO (latest versions of each, of course, since we had another update today), and I hope that solves your issue.

Thanks!

Ok, finally nailed it.
For some reason my system didn’t show me there was an update to the base Event Calendar plugin and hence I thought I was on the latest version. I had ver 4.1.0.1 running. 4.1.0.1 is definitely not compatible with Events Calendar Pro 4.1.1 and above it turns out.
Deleting the Event Calendar plugin and uploading manually the latest version sorted out the issue.

Don’t know if you have any idea as to why the detection of a newer version available wasn’t working on Event Calendar?

best regards /Niclas

I’m very glad to hear you got it figured out. I haven’t heard of this situation before, but sorry you experienced it.

Have a great weekend!
