[Resolved] Wordpress admin gets stuck

Hi,

Which WPML version are you trying to update from?
The latest version of WPML is 4.7.3.
Are you trying to update from a very old version?

Please share your site's Debug information if you need further help with this issue. You can read about it here.

http://wpml.org/faq/provide-debug-information-faster-support/

Thanks,
Itamar.

Hi,

Do you use the WPML CMS Nav add-on?

I ask this question because this plugin adds a particular feature, and by checking your website, I'm unsure if you are using this feature. You can read about the WPML CMS Nav add-on here: https://wpml.org/documentation/support/cms-navigation/.

So if you do not need the features that this add-on adds, simply deactivate it and remove it from your website.

Please let me know if this is the case.

Otherwise, you should not have any problem updating WPML from version 4.6.13. However, you must correct the following.

The debug info you have attached shows that your server's WP Memory Limit is set to 40 M. Our recommendations are to have the following as minimal requirements:

- PHP 7 and above (this is OK with your installation) with a WP Memory Limit of at least 128MB, while 256MB is recommended.

MySQL 5.6 and above.

Please follow this link for detailed documentation:

https://wpml.org/home/minimum-requirements/

Is it possible for you to change those to the minimum requirement?

You may need to contact your hosting provider for that. Meeting those baseline requirements is most critical before debugging, and sometimes solves issues you experience. The most important thing is to raise the WP Memory Limit. Please try to resolve the issue before contacting your hosting company. You can do it from the wp-config.php file in your WordPress installation. Insert this code in that file:

/** Memory Limit */
define('WP_MEMORY_LIMIT', '256M');
define( 'WP_MAX_MEMORY_LIMIT', '256M' );

Add it before this line:

/* That's all, stop editing! Happy blogging. */

Could you please perform that procedure and see if it helps?
Do you still experience issues updating WPML when the WPML CMS Nav has been removed and the WP Memory Limit has been increased?

Hi,

The code I ask you to add is a standard required by WordPress itself, as well as for most themes and plugins.

You wrote: "The reason why I have to update WPML CMS Nav in the list of updates is because apparently I can only use my WPML translation credits when this plugin is updated."

There is no connection between updating the WPML CMS Nav plugin and using WPML's automatic translation credits.

If you require additional assistance with this, please share the access details to your site with me. Preferably, access to a staging site (a copy of your site on the same server where the issue also occurs). I'm enabling a private message for the following reply.

Hi,

We replied at the same time.

For further investigation of the issue, please try the following.

If the problem persists, please share with us WordPress's debug log (not WPML debug information). Please check this page for instructions.

https://wpml.org/documentation/support/debugging-wpml/

To enable it, open your wp-config.php file and look for

define('WP_DEBUG', false);

Change it to:

define('WP_DEBUG', true);
// Enable Debug logging to the /wp-content/debug.log file
define('WP_DEBUG_LOG', true);
// Disable display of errors and warnings
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);

After this, repeat the action that causes the problem on your site - try to update WPML Multilingual CMS (our core plugin.) In this case, the errors will be saved to a debug.log log file inside the /wp-content/ directory. Then, please share the errors with us.

If it's too complicated for you, please refer to my previous reply and share access to your website.

Regards,
Itamar.

Hi,

Important!
Our forum is public. It is not a private discussion or thread between you and us. So, please refrain from posting sensitive information in public replies. I have hidden the login details from the previous reply. For the safety of your site, consider updating those details.

Please allow me to take a copy of your site. For this, I must install a plugin like Duplicator or All In One Migration. Please let me know if you agree.

Regards,
Itamar.

Hi,

I appreciate your patience.

I installed the All In One Migration plugin on your site and made a copy of it. After downloading the copy I deactivated and removed the All In One Migration plugin.

I've debugged this issue with a copy of your site on my local server and found out the following. The problem occurs when WPML is updated to its latest version 4.7.3. Then there is the following fatal error.

Fatal error: Array and string offset access syntax with curly braces is no longer supported in \wp-content\plugins\lionthemes-helper\less\lessc.inc.php on line 749

The problem of fatal error is a collision with your theme, the Hermes theme by Lionthemes88, and with its required plugin, the LionThemes Helper plugin. I then checked further and found out that you are using old versions of the Hermes theme and its LionThemes Helper plugin. I checked their page on Themeforest and could see that the latest version of the theme is version 1.8.9, updated on 14 Apr 2025. You can see it here:
hidden link
The version of the Hermes theme on your site is Version 1.5, which is a 2018 release.

Please update the Hermes theme and its LionThemes Helper plugin on your site; this should hopefully resolve the fatal error on your site when WPML is on its latest version.

**** Important! Please make a full site backup (files and DB) before you proceed with those steps****

Important note!
The Hermes theme by Lionthemes88 is not known to us and is not officially compatible with WPML. It does not mean that it will not work with WPML (when it is on its latest version). It simply means that we cannot be certain. It would be great if you could contact the authors and urge them to join our Go Global Program. You can find details about it here.

https://wpml.org/documentation/theme-compatibility/go-global-program/

We will be happy to cooperate with the authors in making their plugin officially compatible with WPML.

Please let me know how it goes.

Regards,
Itamar.
