Critical error accessing dashboars and tool link

Hi @gustavornunes

I hope you’re well today!

I understand that you have also did a full conflict test (as suggested in that other topic) and it didn’t reveal any conflict, right?

While it may sound a bit “weird”, could you please try reinstalling the plugin?

If that doesn’t help, please try this:
– go to your site’s “Tools -> Site Health” page -> “Info” tab (note that I’m not referring to “Defender -> Tools” page but to WordPress Site Health tool
– expand the “Server” tab and chck the value for “PHP memory limit” (note it down)
– then expand “WordPress Constants” tab and check the value for “WP_MEMORY_LIMIT”

– if this one is lower than PHP memory limit, add following line to the “wp-config.php” file of your site

define(‘WP_MEMORY_LIMIT’, ‘XXX’ );

where XXX would should be the same value that you read from PHP memory limit. Make sure that line is added above the “/* That’s all, stop editing */” line.

If this still doesn’t help, let me know please if your WordPress and all the plugins (including Defender) are all up to date and:

– what webserver is your host using – is it Apache or Nginx or a hybrid “Nginx + Apache” setup?
– what’s the PHP version powering your site?

Best regards,

Hi @gustavornunes

Would you be able to upgrade PHP to a newer/higher version?

We do our best to keep our plugins as backwards compatible as possible but the recommended version is the same as recommended for WordPress, which is 7.4 at minimum:

Sometimes it’s just not possible to keep the plugin fully compatible with older version of PHP without sacrificing some of its features/options so that’s why it’s important to follow the official WordPress recommendations on this.

If PHP update still doesn’t solve it, please let us know here.

Kind regards,
Adam
