When trying to login to my wordpress website the screen goes completely white, I searched the net and tested some possible solutions:
I increased memory for wordpress (that was not the problem)
I renamed the plugin folder to plugin_old and created a new plugin folder, and I also did this in plugin by plugin (that was not the problem)
I can see that it can also be the theme, I rename the folder name of my active plugin and secondly, wordpress would return my site to the default theme but what happened was that the whole site has now gone white.
I gave a debug in wp-config and all the problems that appear on the login screen are related to the widget "The constructor method called for WP_Widget in mad_widget_social_links has been deprecated since version 4.3.0! __construct () ", but I can not find where the call is so I can change it. I think it might be on the same theme but I can not find it. so I can not go to the screen that was white before and see if there is another type of error.
