Suddenly we see new strange problems that we would like you to examine:

1. After CUSTOMIZING some areas of the Soledad theme, we click 'PUBLISH" and it throws up these strange ERRORS about "special characters must be escaped : [<]. 
(Please see images attached)

2. The Wordpress editing window (using classic format) continues to open/revert to TEXT mode. We open it in VISUAL, and soon it automatically reverts to TEXT.

3. On the HOMEPAGE there is a big empty space/ gap between the bottom of the CAROUSEL and the top of the blog posts (in double column). (See image)

Much obliged!

ADDITIONAL NOTE:

It's interesting that when I log in as an administrator, the website behaves much more normally, with the HOMEPAGE immediately loading all the images, etc. 

Autoload options seem to be out of order and malfunctioning. The Homepage does not load most images. The strange thing is that the website loading speed seems to be excellent (Rating100, at about 43ms), according to pingdom tools. The INSIDE pages seem to operate more normally. 

We have not been able to tell if the problem is with the object cache, some plugin or combination of plugins, the PHP version, or the Penci plugin(s). About a minute ago, when going to the homepage, we got a huge list of warnings like this (it seems to involve a very important plugin, SHORTCODES ULTIMATE):


1. Warning: FS_Plugin_Plan::__construct(): The script tried to access a property on an incomplete object. Please ensure that the class definition "FS_Plugin_Plan" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide an autoloader to load the class definition in /home/greanvillepost/public_html/wp-content/plugins/shortcodes-ultimate-pro/freemius/includes/entities/class-fs-plugin-plan.php on line 113

2. The Wordpress installation is warning that the autoloaded options could be damaging performance (??)
This is the warning:

Autoloaded options are configuration settings for plugins and themes that are automatically loaded with every page load in WordPress. Having too many autoloaded options can slow down your site. Your site has 4452 autoloaded options (size: 4 MB) in the options table, which could cause your site to be slow. You can review the options being autoloaded in your database and remove any options that are no longer needed by your site.

BECAUSE the SHORTCODES ULTIMATE threw up the big warning/error you see in #1) above, we tried to DEACTIVATE this plugin and got this warning/error alert:

Fatal error: Uncaught TypeError: unserialize(): Argument #1 ($data) must be of type string, array given in /home/greanvillepost/public_html/wp-content/plugins/airlift/wp_admin.php:272 Stack trace: #0 /home/greanvillepost/public_html/wp-content/plugins/airlift/wp_admin.php(272): unserialize(Array) #1 /home/greanvillepost/public_html/wp-includes/class-wp-hook.php(324): ALWPAdmin->enqueue_deactivation_feedback_assets('plugins.php') #2 /home/greanvillepost/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(NULL, Array) #3 /home/greanvillepost/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #4 /home/greanvillepost/public_html/wp-admin/admin-header.php(118): do_action('admin_enqueue_s...', 'plugins.php') #5 /home/greanvillepost/public_html/wp-admin/plugins.php(637): require_once('/home/greanvill...') #6 {main} thrown in /home/greanvillepost/public_html/wp-content/plugins/airlift/wp_admin.php on line 272
