Title: Can't access admin panel Last modified: August 24, 2016 --- # Can't access admin panel * Resolved [Ali Madab](https://wordpress.org/support/users/ali-madab/) * (@ali-madab) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/) * Okay, I was not careful, but it could give a warning message before doing it, couldn’t it?:) * So there is a multisite wordpress installation. I just added define(‘WP_CACHE’, true); at the and of the file and pressed update. And no, I haven’t done backup of wp config file, but I have a full backup on server. However I would like to restore old wp config and all changes that has been done with my “update” click, because I have worked a lot after backup and before pressing “update”. * I would be thankful to know: * 1. What did I do wrog? * 2. Why can’t I access my admin panel with my account anymore? * 3. Is there anything else has been changed? * 4. How Do I recover the state before? * 5. Are you going to add that warning message in coming version?:) * Please answer as soon as possible. * [https://wordpress.org/plugins/wp-config-file-editor/](https://wordpress.org/plugins/wp-config-file-editor/) Viewing 15 replies - 1 through 15 (of 20 total) 1 [2](https://wordpress.org/support/topic/cant-access-admin-panel-26/page/2/?output_format=md) [→](https://wordpress.org/support/topic/cant-access-admin-panel-26/page/2/?output_format=md) * Thread Starter [Ali Madab](https://wordpress.org/support/users/ali-madab/) * (@ali-madab) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/#post-6089791) * Forgot to say: I have NO FTP access to the host, otherwise I wouldn’t use this plugin to edit wp-config.php. I don’t want to request for credentials of FTP account, if there is a way accessing admin panel without it. * Plugin Author [Code Machine](https://wordpress.org/support/users/xpointer/) * (@xpointer) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/#post-6089863) * 1. What error you’re getting when trying to access? 2. Is the login page displayed but you just cannot login? 3. Is there any visible error message displayed? 4. Did you update wp-config.php file using EDITOR or using FORM? * Using the FORM: This Plugin will only writes those fields in the FORM page. It will erase all the old file and generate new one with the supported fields only. * Using Editor: It will save the file exactly edited by admin so everything should work fine with no problems. * MU installation has specific constants that is not generated by the Plugin yet. May be in later versions, but now it won’t work with MU installation * You need to write MU installation manually back to wp-config.php file. [http://codex.wordpress.org/Create_A_Network](http://codex.wordpress.org/Create_A_Network). You cannot do that without successfully login to WordPress or through FTP * I will create Backup solution to be releases in the next version. I will do that really soon. * Thread Starter [Ali Madab](https://wordpress.org/support/users/ali-madab/) * (@ali-madab) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/#post-6089866) * Hello Ahmed, * Thank you for your response. * 1. ERROR: Invalid username. Lost your password? * 2. Yes. * 3. Yes, see 1. * 4. I updated wp-config.php using Editor. I pressed preview, then added the line( define(‘WP_CACHE’, true);) then I pressed update. Suddenly I am loged out and getting error: invalid usaername trying to login. * I would like to know: Why can’t I login? **How come my credentials won’t work**: invalid username? Do you have an explanation for this? * **What do I do now?** * Why should I manually install MU, **if the only file was changed was wp-config. php?** Why can’t I restore it from my backup and get everything back to normal? * Plugin Author [Code Machine](https://wordpress.org/support/users/xpointer/) * (@xpointer) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/#post-6089868) * You lost MU configuration after saved wp-config.php file * You must revert this through FTP. wp-config. file is what telling WordPress about MU configuration. All MU parameters is there. * “Using Editor: It will save the file exactly edited by admin so everything should work fine with no problems.” ==> This is not correct. I’m sorry. * It will always erase CUSTOM fields as I mentioned in the Plugin page. * I just want to make sure its not Secure Keys issues. Please try Login from another Browser. If you still unable to login then you’ve to write them through FTP * Plugin Author [Code Machine](https://wordpress.org/support/users/xpointer/) * (@xpointer) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/#post-6089869) * I can help you on that but I must have FTP access * Thread Starter [Ali Madab](https://wordpress.org/support/users/ali-madab/) * (@ali-madab) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/#post-6089875) * I am sorry, but I’m not allowed to give any access to third person. But thank you very much for offering your help. * So everything I need to do, is getting old wp-config.php file recovered, right? Are there many wp-config.php files for MU? * Thread Starter [Ali Madab](https://wordpress.org/support/users/ali-madab/) * (@ali-madab) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/#post-6089878) * I am not able to create a FTP connection, but I have access to database.

I brought back only wp-config.php file and everything is alright now. * One BIG request! * Either change the name of your plugin to “restore default wp-config.php file ( only english version)” or make it really an editing plugin, not restoring. It has overwritten the whole file and I lost a lot of time to recover it. * BUT thank you for the free plugin and I wish you luck! * If I can’t help somehow, please let me know. * Plugin Author [Code Machine](https://wordpress.org/support/users/xpointer/) * (@xpointer) * [11 years ago](https://wordpress.org/support/topic/cant-access-admin-panel-26/#post-6089930) * I really appreciate your comments regards the Plugin * I’m really sorry wasting your valuable time. * I created this Plugin and still waiting Community Reviews. * Its BETA Plugin currently version 0.5 * I’m waiting to see if its really useful. If it helps users I will add a huge number of features to this Plugin. I’ve already wrote a list of features but I need to verify that the concept is required. * Glad you got everything works fine.
