PROBLEMS INSTALLING E NEWSLETTER PLUGIN

I wiped the downloaded plugin file and uploaded it to the install new plugin, but then I get this message:
Installing Plugin from uploaded file: email-newsletter-files.zip
Unpacking the package…

Installing the plugin…

The package could not be installed. No valid plugins were found.

Plugin install failed.<strong

    Hello Magnus,

    I hope you're well today and thank you for your question!

    I'm not sure what exactly did you do to the plugin and what's included in the file that you're trying to install e-Newsletter plugin from but here are my suggestions :slight_smile:

    The simplest way to install any of our plugins is to use our "WPMU DEV Dashboard" plugin:
    https://premium.wpmudev.org/project/wpmu-dev-dashboard/

    If it is installed on your site, please go to your dashboard's

    "WPMU DEV -> Plugins" page

    and type "e-Newsletter" in search window. The plugin will show up so you will only need to click "Install" button and it will be automatically downloaded and installed on your site.

    Alternatively, please go to this page:

    https://premium.wpmudev.org/project/e-newsletter/

    When you're logged in into your WPMU DEV account you should see a gray "Download plugin" link there. Use it do download plugin .zip archive and once it's downloaded go to your dashboard's

    "Plugins -> Add New" page

    - click on "Upload Plugin" button
    - use "Browse" button to select the file that you've just downloaded
    - use "Install" button to install the plugin.

    Assuming that you're indeed referring to our "e-Newsletter" plugin this should help. The file name that you mentioned in your question doesn't seem to be right so I suppose that's not an original plugin installation file and that's why it doesn't install well. Solution that I suggested above should then let you install the plugin.

    Let me know please if it worked for you!
    Best regards,
    Adam

    Hello Magnus,

    Thank you for your replay!

    It seems that you managed to install the plugin but there's still something going not exactly right. I'd like to take a closer look at it. Would you mind granting me a support access to it so I could further investigate the issue?

    Here's a guide on how to do this:

    Hello Magnus,

    Thanks for granting an access.

    I've visited your site and checked its settings. I've found that despite the error some newsletter were created although still - they're not available for editing. Furthermore, in both cases (creation of a new newsletter and editing existing one) the server returns a "500 Internal server" error response (this is visible in Chrome's developers console).

    Unfortunately, this is one of the most unspecified HTTP errors and it doesn't say much about its own causes. Usually though it's caused by an insufficient memory amount assigned to WordPress. Therefore I checked your install and it turns out the the WP memory seems to be limited to only 40MB which is extremely low amount.

    That said, I think we should try increasing that limit and hopefully this should solve the issue. Your PHP limit on the server is set to 256M so let's use the same for WordPress. To do this, please add following line to your site's "wp-config.php" file:

    define('WP_MEMORY_LIMIT', '256M');

    The line should be placed above the "/*That's all, stop editing.... " line.

    Add it there please, then clear all site caches (including WPEngine cache for your site if possible and your browser's cache) and give it another try.

    Let me know if it helped, please!
    Best regards,
    Adam

    Hello Magnus,

    Thanks for re-granting access.

    I checked your site again and I think some more debugging is needed. I'd like to ask you to perform following tasks, would you please be so kind?

    1. Add following lines to your "wp-config.php" file:

    define('WP_DEBUG',true);
    define('WP_DEBUG_LOG',true);

    These lines should be placed anywhere above the "/*That's all, stop editing..." line.

    2. Run a full theme/plugin conflict test as described on a flowchart in this article:

    https://premium.wpmudev.org/manuals/using-wpmu-dev/getting-support/

    Hopefully, the "create newsletter" function should work with default theme and no other plugins active and then stop at some point. This would tell us if the theme is interfering here or a plugin (and which one).

    3. Let me know about test result and please also share the content of a "/wp-content/debug.log" file that will appear on your server (you may need to access your site via FTP or cPanel File Manager to be able to download that file).

    Thanks!
    Best regards,
    Adam

    Hi Adam, we have done the things you described and it seems to be a conflict with the plugin: de_multirating av JobEngine.

    Here is also the debug log:

    Hello Magnus!

    Ok Predrag, will you be able to make a work around this?

    This may be possible, though I'd prefer not to share any estimations yet. If necessary I'll involve ENewsletter developer in this. However I'd like to confirm for sure first that this is indeed theme issue. As you previously responded that you did not try it with the default theme could you please switch the site temporarily to Twenty Fifteen and make sure that the plugin is working with it?

    Also, is there any staging site (1:1 copy) of your live site where we could safely make changes and tests without affecting your live setup? This would be very helpful as the theme that you're using is a premium theme and I do not have any access to it.

    That said, it would be great if there was a staging/dev site but we'll find other way to work on this if this is not available.

    Looking forward for your answer to my two questions above and I'll be happy to assist you further then.

    Best regards,
    Adam

    Hello Magnus!

    I suggested setting up a staging site for safety of your current site. Unfortunately, it happens sometimes that the plugin - this actually applies to any plugin, not just ours - behaves in a different way than expected and such a complex troubleshooting/investigation is necessary to make it work. Some issues are extremely difficult or pretty impossible to discover during pre-release testing.

    That said, I can understand your point. It would be great though if you could perform at least that one last term to confirm if this indeed is a theme that's conflicting here. I'd then try to find other way to analyze and fix that.

    Best regards,
    Adam

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
