Title: WordPress 5.9 wp-admin access problem Last modified: January 26, 2022 --- # WordPress 5.9 wp-admin access problem * Resolved [Stephan Jacob](https://wordpress.org/support/users/jimknopf128/) * (@jimknopf128) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/) * Here it goes: – one of my sites was auto-updated to 5.9 (still have to figure out why 😉 – trying to access it, produced an error “Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 72 bytes) in /raid/home/harmony/ harmonyfdn/wp-content/plugins/social-icons-widget-by-wpzoom/includes/icons-data. php on line 14206” – I tried to allocate more memory to WP – can’t access /wp- admin either – I re-named “plugins” to “plugins.hold” – now I can access the site (without plugin features) but /wp-admin produces “There has been a critical error on this website.” * Q: is there another way to get to my dashboard to work on the plugins, likely social-icons-widget-by-wpzoom * Thank you, Stephan Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/page/2/?output_format=md) [→](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/page/2/?output_format=md) * Moderator [t-p](https://wordpress.org/support/users/t-p/) * (@t-p) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/#post-15290857) * First try Try increasing memory allocated to PHP: [https://wordpress.org/support/article/editing-wp-config-php/#increasing-memory-allocated-to-php](https://wordpress.org/support/article/editing-wp-config-php/#increasing-memory-allocated-to-php) * If that does not help, access your server via [SFTP or FTP](https://wordpress.org/support/article/ftp-clients/), or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/plugins/ and rename or delete the directory of `social-icons-widget-by-wpzoom` plugin. * If still no joy, then please review 5.9 [Master List](https://wordpress.org/support/topic/read-this-first-wordpress-5-9/?view=all) and attempt [troubleshooting](https://wordpress.org/support/topic/read-this-first-wordpress-5-9/?view=all#post-15286141) outlined therein. * Moderator [t-p](https://wordpress.org/support/users/t-p/) * (@t-p) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/#post-15290964) * Have attempted troubleshooting suggested in my previous reply? * [kribasic](https://wordpress.org/support/users/kribasic/) * (@kribasic) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/#post-15291907) * I can’t enter the dashboard as well.

It leads me to error 404 page with this URL: …/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F * The problem was that the upgrade.php was blocked at the server level. So I unblocked it, and now I can login without any problem. * [Guido](https://wordpress.org/support/users/guido07111975/) * (@guido07111975) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/#post-15292875) * Hi [@jimknopf128](https://wordpress.org/support/users/jimknopf128/) * The only thing you need to do is changing the name of the social-icons-widget- by-wpzoom folder to de-activate that plugin. 1 character is enough. * But there are other problems with WordPress 5.9, as you can see there are many recent topics created about this unfortunately. * I also had 2 sites that crashed after the update to version 5.9 (500 error). Still not clear what caused this. * Guido * [Guido](https://wordpress.org/support/users/guido07111975/) * (@guido07111975) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/#post-15292948) * If the WordPress crew doesn’t provide a fix anytime soon, I think the best thing to do is to ask your hosting provider to replace a backup. Or maybe you can do this yourself via your hosting panel. * I have also read that this can be casued because the update timed out, this can mean WordPress isn’t fully installed on the server. So files are missing. But am not certain about that. There’s even a post about this update, [check this](https://wordpress.org/support/topic/read-this-first-wordpress-5-9/). * Guido * Thread Starter [Stephan Jacob](https://wordpress.org/support/users/jimknopf128/) * (@jimknopf128) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/#post-15294736) * I’m by no means an expert, but here’s where I’m at today (I posted the original question): * – I updated the PHP version (5.? > 7.4) this was done through the host’s dashboard * – I de-activated all plugins via FTP (added text to each individual plugin folder within wp-content > plugins) * – now I’m re-activating each plugin by 1/ restoring the original plugin folder name 2/ reloading the wp-admin page (to make sure nothing broke) 3/ activating the plugin 4/ reloading the wp-admin page (to make sure nothing broke) 5/ check( reload) the actual site (to make sure nothing broke) * So far I was able to re-activate 4 of 9 plugins, the others seem to cause problems(?). I’m lucky that this site only uses 9 plugins. This is a good reminder to keep the plugin count lean ;). * Hoping for suggestions to streamline the process 😉 * Thank you to the community.

Version 7.4 is also fine. * But if you have ancient plugins, maybe even PHP 7.4 is too much. In that case you must consider replacing those plugins. Same applies to your theme. * Guido * [nhdwordpressorg](https://wordpress.org/support/users/nhdwordpressorg/) * (@nhdwordpressorg) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/#post-15294952) * I have tried * • PHP at 7.4 and 8.1 • Deactivating all plugins • Reverting to WordPress Theme( Twenty Twenty Two) • Adding more memory via PHP * The website is viewing perfectly, yet I still have no access to the Dashboard( wp-admin) page. * Thread Starter [Stephan Jacob](https://wordpress.org/support/users/jimknopf128/) * (@jimknopf128) * [4 years, 4 months ago](https://wordpress.org/support/topic/wordpress-5-9-wp-admin-access-problem/#post-15294958) * Guido, * The site is not that old, and I’m trying to keep everything reasonably up-to- date. I think I saw somewhere that PHP 7.4 is the recommended, stable version? * Thank you for your advice.
