Cannot Access Notify Users Page

How many users do you have? How about groups? Any special meta filters or group management plugins in use?

How do you define your groups? Email Users doesn’t provide any ability to define groups or manage roles. Those sort of tasks must be done with another plugin or with WordPress directly.

1. How many total groups does your site have?
2. How many total users does your site have?

If you use the Dashboard > Email Users > Send to Users function, does it take about the same amount of time for the page to load as it does when you do the Notify Users about this Post function?

My guess is the database query to build the list of users is taking a very long time. Email Users has a debug setting and one of the things it does when debug is enabled is output some information as HTML comments on the Dashboard pages where the the the list of users is presented.

For example, if I navigate to the Dashboard > Email Users > Send to Users page and then look at the HTML source of the page (Ctrl-U) I will find some comments which look like this:

<!-- email-users.php::1386 -->
<!-- email-users.php::1387 -->
<!-- 
Array
(
    [total_users] => 1285
    [avail_roles] => Array
        (
            [administrator] => 1
            [contributor] => 4
            [editor] => 2
            [subscriber] => 1277
            [none] => 1
        )

)
 -->
<!-- email-users.php::1389 -->
<!-- 
Array
(
    [exclude] => Array
        (
            [0] => 1
        )

    [fields] => all
    [offset] => 0
    [number] => 500
)
 -->
<!-- email-users.php::1391 -->
<!-- email-users.php::1410  Query #1  Memory Usage:  15.75M -->
<!-- email-users.php::1410  Query #2  Memory Usage:  20M -->
<!-- email-users.php::1410  Query #3  Memory Usage:  24.25M -->
<!--

<!-- email-users.php::1444 -->

I added this when working with a user who had a very large database of users and memory was being exhausted. The query is broken up into “chunks” to ensure that memory isn’t exhausted.

I could add some additional information to report how long the query is actually taking as I can see how that would be useful in your case. It wouldn’t take me long to do it if you are ok installing a beta version.

Sorry I missed your reply before the weekend. I’ll see if I can get a build put together later tonight.

I’ve posted a new build which will report the time it takes to run the user query.

When running this build in Debug Mode, it will report information like this as comments in the HTML on the Send to Users page:

<!-- email-users.php::1391 -->
<!-- email-users.php::1410  Query #1  Memory Usage:  15.75M -->
<!-- email-users.php::1415  Query #1  Execution:  0.30101704597473s / 301.01704597473ms -->
<!-- email-users.php::1410  Query #2  Memory Usage:  20M -->
<!-- email-users.php::1415  Query #2  Execution:  0.29001688957214s / 290.01688957214ms -->
<!-- email-users.php::1410  Query #3  Memory Usage:  24.5M -->
<!-- email-users.php::1415  Query #3  Execution:  0.201012134552s / 201.012134552ms -->
<!-- 
1282 -->
<!-- email-users.php::1448 -->

I don’t see anything unless you send it to me or post it somewhere. To see what your site is doing, do the following:

1. Download the v4.8.5-beta from my web site.
2. You’ll need to manually install it. The easiest way is via FTP since you can unzip the file and drop it on the existing plugin. If you want to upload it using the WordPress plugin installer, you will need to delete the existing plugin before you can upload the zip file.
3. Once the plugin is installed, Enable Debug from the settings page (Dasboard > Settings > Email Users).
4. Visit the Send to Users page (Dashboard > Email Users > Send to Users) and let the page completely load. I think you stated this was taking minutes to do.
5. Once the page is fully loaded, view the HTML source for the page and look for the comments section like I posted above. It should be in the first 400-600 lines of the HTML.
6. Copy the information and email it to me (mpwalsh8 at gmail dot com) or post it here so we can see what the numbers look like.

Once we see what the numbers look like, we’ll have an idea of where to go next.
