Hello @sydbrown

Would you please go to /var/www/html/wp-content/plugins/w3-total-cache/PgCache_Plugin_Admin.php on line 108 and replace

$crons = _get_cron_array();

with

$crons = ( array ) _get_cron_array();

Hope it helps ?? Please feel free to ask more question if you have any.

Cheers
Ash

Hello @tomstaveley

In addition to Destac, you can submit feature request with your suggestion from Dashboard > Performance > Support section.

Have a good day!

Hi Aldo

This is a nice idea indeed, would you please go to Dashboard > Performance > Support > And create a new feature request from there? This way the request will directly go to the author ??

Have a good day!

@mo7900, is it a single site or multisite? Do you have any plugin that deals with other plugin?

Also, when you update an plugin, the plugin is deactivated first, updates and activated again. Would you please make sure nothing is updated too?

By the way, I have also seen some minor bugs, I hope the developer is keeping his eyes on those too ??

@rodgonz, the latest version of the plugin is not compatible with php version 5.2 anymore. I am not the plugin developer but I believe it won’t be 5.2 compatible again, ever. Also, 5.2 is very outdated. So, it’s better to upgrade php version in the server to at least 5.6.

Are you having any other issues except php version compatibility?

@millerdesignsgraphics, first one looks like the server is down. The second one seems having a fatal error.

As a quick workaround, you can go to /wp-content/plugins/ and rename w3-total-cache to something else. You can use any FTP client software or cpanel file manager, this will bring your sites back.

Now, the latest release doesn’t support php 5.2 anymore, 5.6 is safe. So, would you please make sure you are running minimum php 5.6 in your server?

Have a good day!

@fonta, would you please make sure your php version is at least 5.6? The current version doesn’t support php 5.2 anymore.

If php version is okay for you, then would you please enable debug mode and check if any error is shown in that page?

To enable debug mode please edit a line in your wp-config.php:
Change

define('WP_DEBUG', false);

to

define('WP_DEBUG', true);

Please let us know what errors you see there.

Have a good day!

@aeypushkar, yeah it may conflict. It’s not a good idea to add htaccess code same type of functionality, IMO.

I would take a backup of current htaccess, then use the code that W3TC adds in it to check if the performance increases or not. You are always open to go in trial and error process ??

Have a good day!

Cheers
Ash

Glad I could help ??

If you go to /wp-content/plugins/w3-total-cache/PgCache_Environment.php line no 527 you will see the function that is generating this htaccess code. To be precise it is around line 730. You can modify in there to remove some htaccess that you don’t want.

Please note that, this changes will be lost in next update. So it’s worth to note down this changes somewhere and apply again after your updates.

Have a good day!

@preximosoft, what happens if you deactivate W3 Total Cache plugin? Is it fine then? Just want to make sure if the issue is happening due to W3TC or not. I am asking because, normally W3TC doesn’t cache anything in the backend.

Hello @technically-blonde

I have added the suggested lines
/** Enable W3 Total Cache */
define(‘WP_CACHE’, true); // Added by W3 Total Cache
to wpconfig.php manually

Do you confirm that you didn’t add the code not below of “That’s all……..” message? You need to put the define code above that message.

Please check and let me know.

Have a good day!

Cheers
Ash

If you want to remove w3 total cache, you need to remove advanced-cache.php and cache folder from wp-content folder. And then open your wp-config.php file, if you see there any code related to W3TC, you need to remove those code too.

I have blank page on wp-login.php due the plugin.

This happens mainly for any error. Would you please enable debug mode and check if any error is shown in that page?

To enable debug mode please edit a line in your wp-config.php:
Change

define('WP_DEBUG', false);

to

define('WP_DEBUG', true);

You will see the error in wp-login.php page.

Have a good day!

Cheers
Ash

Hello @fomenkoandrey

First of all, take a full backup of your database.

Then, go to phpmyadmin then in SQL tab, then run the following query:

DELETE * FROM wp_options WHERE option_name LIKE '%w3tc%'

wp_ is the table prefix here, may vary with your installation, so make sure you use the correct prefix according to your setup.

Have a good day!

Cheers
Ash
