Internal Server Error when trying to update to 3.5.2

[jeataylor]

Tried to update to Events Calendar Pro 3.5.2 after updating The Events Calendar to 3.5. Get an Internal Server Error. Reverted back to 3.4.1 & 3.4 respectively to get site functioning again. Now I have duplicated events.

The only errors I can find in the server logs are:
mod_fcgid: read data timeout in 120 seconds, referer http://levinjcc.org/wp-admin/network/update.php?action=upload-plugin

End of script output before headers: plugins.php, referer http://levinjcc.org/wp-admin/network/update.php?action=upload-plugin

How can I remove the duplicated events? I have over 11,000 events.

Hello jeataylor,

Thanks for contacting us, sorry you are experiencing this! This has been an issue for quite a few users this last few weeks, but we have it resolved.

This press release should answer your questions I believe. It’s best to upgrade directly to 3.5.2, and in the press release you will find a plugin to remove the duplicate events.

Please make sure you have a recent backup of you site before you start! I’m assuming nothing bad will happen, but better to be safe than sorry. It sounds like you already have one; if you do you’re set!

Does this make sense? Let me know if I can explain anything else!

Sorry for the difficulties, we’re hear to help in anyway we can.

Cheers!

Hi, I’ve tried upgrading to 3.5.2. I’m using a multisite setup and when I go to “network activate” the plugin, I get the Internal Server Error which locks up the admin area. The only way I can unlock is to go back to 3.4.1.

I had no problem updating to 3.5.2 and network activating on my local MAMP install.

That’s a bummer!

In the WP-Admin, at the bottom of the Events > Settings > Help tab, there will be a ‘systems settings’ box. Can you copy that and paste it into a private reply?

Can you do this for both your local and production servers? I’d like to know if there is a difference in environments.

Thanks for your patience on this, most of our team is out today and I haven’t seen this one before.

Hello jeataylor,

Here is the scenario as I understand it.

Many people had difficulties upgrading to Pro 3.5 because of a mysql conversion script in the upgrade process. The script timed out on smaller machines, creating duplicates. I believe this is why you could upgrade just fine on your localhost, as it is presumably more powerful than you server (dedicated machine vs virtual shared instance). This is just a hunch though.

Could you expand on this a bit more?

I’ve tried upgrading to 3.5.2. I’m using a multisite setup and when I go to “network activate” the plugin, I get the Internal Server Error which locks up the admin area. The only way I can unlock is to go back to 3.4.1.

In what way does it lock up? Is the whole admin system blank?

Ideally in this situation, you would first deactivate both plugins before updating them at the same time, possibly upgrading to 3.5 first.

Does this make sense? Let me know if this doesn’t work for you.

Cheers!

Still having trouble. I deactivated both plugins, updated to 3.5 first for both. Network Activated TEC first no problem. Then network activated ECP at which time I got the Internal Server Error. If I try to access any area of admin, I get the Internal Server Error. Only way to get the Internal Server Error to go away is to delete ECP from server. Then I can install 3.4.1.

For what it’s worth site is hosted on GoDaddy.

Sorry for the delayed response. Because of the difference in local and production, this is a trickier problem so I had a developer take a look at it.

The next best thing to try unfortunately is to disable all plugins switch to a standard theme, then update and reactivate everything.

Does this make sense? I apologize for the extra steps, but there is a limit on troubleshooting techniques at this level. Let me know if this doesn’t work for you.

Cheers!

Ok, We get a decent amount of traffic on the site on a daily basis. Do you think I can use a maintenance mode plugin while doing this? So, disable all plugins but the maintenance mode one, switch to twentytwelve, update & reactivate.

Thanks for your help so far. This has been frustrating because it is holding me up on starting a build on a second site of the multisite that will be using ECP with Community Events and the Filter Bar.

[Casey D]

As a developer and sysadmin I definitely empathize with your frustration. When there is a functioning difference between two identical instances, troubleshooting ideas dry up fast. 🙁

The maintenance plugin sounds like good idea. Depending on the size of your site, I can’t imagine it would take too long to update, especially if you do it during a traffic lull.

Please make sure you have a recent backup of your site before you start! I’m assuming nothing bad will happen, but better to be safe than sorry. I’m assuming you already know this, but still wanted to make an effort to have your bases covered.

Let me know how it works out!
