PHP Fatal Error

I’m getting the same fatal error. Some mismatch with different versions of guzzle I think.

Same issue.

Best regards.

Tested the new version 2.3.2 and get the same fatal error.

Any news about this issue?

Best regards.

Hi, I am also getting same error on latest plugin 2.3.2

I open a new thread to see if any of the authors deigns to respond and provide a solution to this issue ??

Best regards.

Same here, but on version 2.3.4.

We want to get this issue resolved as quickly as possible. We don’t normally provide support through public channels but since this is an issue with multiple threads and since it is causing a fatal error we do want to find the cause and provide a solution.

In future please route issues through our official support channel and they will get handled quickly. Issues of this severity can be escalated to the tech team and we can provide better support through those channels. ActiveCampaign Help Request

You can also email [email protected] with an issue.

For this particular issue we will work with you all to try and resolve this here in this post.

We have not been able to reproduce the error as reported. We have tried every potential update path and have yet to encounter the exact error you are all facing. The last few minor versions have contained changes hoping to address the issue but it appears to be something specific you might have in common.

It sounds like maybe the common cause starts at being on version 2.3.0 of our plugin and being stuck unable to update the plugin. In this case have you been able to manually update the plugin by installing it either via FTP or through add new plugin? Is there a specific plugin, theme, or customization that is conflicting with our plugin?

Do any of these steps help? Can you manually remove the plugin or overwrite the existing one and install version 2.3.4 successfully?
https://kinsta.com/knowledgebase/installation-failed-destination-folder-already-exists/

Is anyone using the WooCommerce High-Performance order storage (COT) feature? We are aware that the plugin is not yet compatible with this update and will be addressing that soon but as of right now our plugin is likely not compatible.

Is it potentially a specific configuration on your host or are you running a certain customization of WordPress through a host?
Is there a commonality with PHP, WP, or WC versions? We have tested up to PHP 8.0, WP 6.2.2, & WC 7.9.0.

In the database does it solve the issue if you delete the following wp_options rows?
activecampaign_for_woocommerce_settings, & activecampaign_for_woocommerce_storage

Is it a file permission issue with our plugin specifically?

I have noticed in the stack traces shared there are conflicts with our vendor guzzle package.
One was activecampaign-tools. This is not associated with our plugin and may be causing a conflict.
Another was wp-scheduled-posts.

Can anyone provide information as to which plugins these are and which versions you are on? If it is a conflict maybe we can trace the cause and either resolve it on our end or work with the creator of the conflicting plugin to resolve.

Any extra information you can provide will help us determine a cause for the problem and hopefully replicate the issue.

We have some good news. It looks like the issues are in fact due to a conflict with one or more other plugins. Dependency management conflicts with composer are a widespread problem in WordPress but fortunately we can resolve this on our end so we know that our plugin isn’t contributing to the problem. We are testing the fix and it will go out as soon as the update clears testing.

Just for future knowledge when you do run into an issue like this and you find a stack trace, if you analyze the paths you might see 2 or more plugins in that stack history. Here are a few example from above in your traces.

wp-content/plugins/activecampaign-tools
wp-content/plugins/activecampaign-for-woocommerce

also

wp-content/plugins/eboov/includes/aws
wp-content/plugins/activecampaign-for-woocommerce

If you look through the trace you might see our plugin and some other plugin mentioned. This issue will only happen if you run a plugin that just so happens to have the same vendor packages loaded the same way with the same namespace. This is the first sign you have a plugin conflict as the cause. Resolving this may require one or both plugins have to make code adjustments. Who is at fault isn’t always clear in these cases especially if what was done isn’t abnormal according to WP coding standards but it does happen.

Even though we are fixing this issue on our end be aware that the other plugin mentioned could potentially have conflicts with other plugins. It’s worth mentioning this issue to the other plugin managers as well since this case means they could still conflict with other plugins you might install.

We do try to address issues as soon as they are reported but we do have far more capability to address those quickly and more fully when you go through the ActiveCampaign support channel. Thank you for making us aware of this and I will inform the thread when we deploy this fix.

Yes, we’re using ActiveCampaign for WooCommerce and ActiveCampaign Tools.

Best regards.

Version 2.4.0 was just released with a fix to avoid conflicts. I won’t mark this resolved just yet until we hear back from you all. If the issue continues, please let us know. We’ll give it some time to see if anyone still encounters the issue. If not we’ll close the related threads.

Sorry but doesn’t work ??

Best regards.

@artprojectgroup It looks like from your stack trace that your issue is with a plugin conflict not associated with our plugin. A plugin called activecampaign-tools and fusion-builder not activecampaign-for-woocommerce. I’m not aware of an activecampaign tools plugin so if this is a product we own I will look further into it otherwise you may want to open a support ticket with either activecampaign-tools or fusion-builder as the issue at this point appears to be on their plugin.

Sorry, you are right, which is generating the issue is ActiveCampaign Tools and as far as I can see it is totally abandoned. I have tried to update its libraries but it keeps returning error.

We will have to evaluate its elimination.

Best regards.

Working after updating some ActiveCampaign Tools libraries and codes.

Thank you very much.

Best regards.
