Hi, what’s the error you are getting when you try to access backend, after increasing memory limit to 128M ?

[JPQB]

after the activation of Hide My WP plugins the error always shows every time i access mydomain.com/wp-admin and the message is Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

The Hostgator admin done in adjusting my php memory settings to 256M

Hi, the memory limit 256M should be enough.

Please create a PHP file (info.php) in your site’s root directory and add following code in it:

Now access it with http://www.yourdomain.com/info.php and check “memory_limit”. Is it 256M there?

Hi, I’ve assigned this ticket to Sr. Support so that he can look further into it.

Hello there,

Sorry for delay, there was another customer with similar issue and I responded him by email. Maybe, I guested it’s a duplicate query.

Anyway, this message may be caused by any other plugins or theme or even WP itself. In fact, WP had similar problems before. So it’s not possible for us to regenerate it.

As, it take so long, you’re already qualified for a refund but please still follow this small guide and help us for similar issues. Even after refund you can use our plugin in your site.

To see the real error please open your plugin editor choose Hide My WP in this file: hide-my-wp.php search for ob_starter then change this line (add // before it):

ob_start(array(&$this, "global_html_filter"));

to

// ob_start(array(&$this, "global_html_filter"));

Then check your site for any error message. If you don’t see anything please a href=”https://codex.wordpress.org/Debugging_in_WordPress#WP_DEBUG”>enable WP debug mode

If you think it’s complex please provide credential details (WP+FTP) with a private reply and I will do it.

Seems strange. I also requested FTP so if it goes wrong I can deactivate the plugin.

Hi-

After doing many tests here is what I could understand:

Without a doubt it’s a memory usage problem. It wasn’t fixed by increasing max memory limit because it was not caused because of an explicit limit but it’s an out of memory problem. In other words, if your computer has 1GB memory and you set the memory limit to 4GB it doesn’t mean you can use more than 1GB. Disabling Jetpck helped because it decreased memory usage not because there’s an issue with it.

I configured your site to use PHP 7.0 and this completely solved the problem (Note that PHP 7 uses about 50% less memory than PHP 5.x). Unfortunately, there was an incompatibility with PHP 7 and one of your other plugins (or maybe your theme).

As Hostgator suggested here (out of memory section), it’s better to contact with their support department.

Send these lines as reference (74186752 means about 70MB):

[13-May-2016 11:07:38 UTC] PHP Fatal error:  Out of memory (allocated 74186752) (tried to allocate 180224 bytes) in /home1/q3e5b0o1/public_html/wp-content/plugins/wordfence/lib/menu_scan.php on line 99
[13-May-2016 11:07:38 UTC] PHP Fatal error:  Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

Let me know the result.
