    It seems that this plugin registers its libraries long before it needs to use them. In particular, the Google SDK. This means that another plugin, which has a different version of the Google SDK (e.g. an older one because of a need to support older WP/PHP versions), cannot do so, because this plugin got there first and inserted something incompatible.

    In our case (UpdraftPlus, 1 million installs), we have had a report from a user who cannot send a backup to Google Drive, getting the error given below.

    There’s no need for your plugin to load its Google SDK before the point at which Google is being contacted. On a backup job – run via WP cron, as a background task – there’s surely no need for a Google Analytics plugin to be doing anything?

  • hi @davidanderson,

    Thanks for noting this issue. We are aware of it.

    Currently there are many plugins using Google SDK, its different versions and its different services and other third-party dependencies. There are new and old versions of Google SDK as well as its versions for PHP 5.4+ and PHP 5.5+.

    Google SDK has quite a large size. Some plugins remove its services and do not load whole SDK. Google Analytics checks whether any plugin loaded SDK before, and if it is so, our plugin does not load SDK and uses other plugin’s instance. We hope that any plugin which uses Google SDK, includes its full version. And we also do not strip any service needed for other plugins from our version. Note that we can’t prefix Google SDK. Therefore there is only one instance of SDK running in WP code, and it needs to be whole.

    We need to find optimal solution which causes minimal compatibility issues.
    Note, that Web-Dorado also has several other plugins using Google SDK, including Backup plugin which is compatible with Google Analytics WD.

    So we decided to
    1). Use it’s latest version
    2). PHP 5.4+
    3.) load SDK fully
    4). load it quite early

    Even if we include Google SDK later, this will still cause compatibility issue with your plugin. We can’t switch back to the older version, because of compatibility issues with other plugins. Can’t you move forward and update the Google library and include it’s full version ?


    Thanks for getting back. It’s 4) that’s the problem: loading early. You say…

    Even if we include Google SDK later, this will still cause compatibility issue with your plugin.

    How would it cause a compatibility problem? It shouldn’t, if it is late enough… i.e. just before any API calls that you make to Google. Because, I think that your plugin will *never* need to make an API call to Google within the same PHP invocation as our plugin makes an API call to Google. i.e. There will then never be a situation when we both want to load our SDKs.

    We only load our copy of the Google SDK at the moment of contacting Google to send a backup. Since that’s in the background, that can never cause another plugin a problem, because no other (sane) plugin can be calling Google for anything at that time. Typically, we’ve been called from wp-cron.php, calling our registered action for a scheduled backup. There’s no situation in which the same PHP process will want to talk to the Google Analytics API, and also talk to the Google Drive API. These will only happen in different PHP processes.

    So, I think that loading late (only when you know that you’re about to make a Google API call) can work.

    We can’t switch Google SDK version. It would (according to https://wordpress.org/about/stats/) mean breaking around 200,000 sites of our existing users, who are on PHP versions older than PHP 5.4.

    Loading early is the wrong thing to do. If every plugin did that, it would be complete chaos. If we loaded ours early, then we’d break every user who uses your plugin. Loading late is the way to co-operate nicely with other plugins.



    thanks for your suggestion. We took a look at the issue, but could not reproduce the error.

    Can you please provide typical stack trace for the code throwing error?
    Does it include plugins_loaded and inithooks actions?

    If backup code runs earlier, we will move loading of Google SDK into these two hooks.
    Since GAWD plugin needs Google API data in it’s core functionality, I don’t think we can include the library later.

    Sorry, I don’t understand. How can anything in a plugin run earlier than plugins_loaded ? That’s the hook that WP’s code for loading plugins uses to indicate that activated plugins have now been loaded. That’s early in the WP bootstrap process, so *nothing* of any use that’s triggered by WP (e.g. cron events) can even *theoretically* run before that.

    You just need to move the loading of the SDK to the same place where you make the API calls. i.e. Wherever in your SDK communicates with Google, put the loading of the SDK just there, and no earlier. That’s what we do with UpdraftPlus, which is why you’re not getting any reports from UpdraftPlus users that they can’t use your plugin because of a conflict… as long as all plugins co-operate nicely like this, then everything can co-exist.


    Here’s a strack trace up to the routine in which UpdraftPlus is about to send a just-created backup to Google Drive (when created by pressing “Backup Now” in the admin area, so this isn’t the cron case). At this point, it hasn’t yet loaded the Google Drive SDK (this happens next)… but has a problem if some other plugin already has. (No other plugin has a good reason to… because it’s an AJAX request sent to UpdraftPlus. Particularly, there’s no reason why in this PHP process invocation there’d be Analytics activity going on; there’s nothing in a back-end admin AJAX request to another plugin that involves a need to talk to Google Analytics).

    Thanks for your comments,

    We checked the problem again and discovered that there are definitely some things to fix in Google Analytics WD plugin. Plugins_loaded hook is used where it is not necessary and Google SDK is loaded too early. We will fix this issue ASAP. However it will require refactoring of large chunks of code, so it may take some time. The fix will be released within several weeks.

    Thank you again very much! We owe you one 🙂

    Hi Tigran,

    Thank you very much!



    Did this get fixed? We’ve had another report from a user facing this problem.


    Hi, David!

    Unfortunately, the version with this fix hasn’t been released yet. Most likely, the patch will be available next week.

    Nevertheless, we can provide you with a beta version that’s still being tested.

    If you’re interested, please contact Web-Dorado Customer Care at support@web-dorado.com and we will send you the beta package of the plugin.
