Error decoding: JSON data control character error possibly incorrectly encrypted

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

A client's website started showing this like a week ago or a little bit more.

I tried disabling plugins, components, etc. Nothing worked until I figured out that it happened only to logged in users who were working on the site and also trying to see frontpage.

On my Joomla config, I changed the settings to PHP, reduced the cache time to 5min and set the Shared sessions to off. 

So far, I haven't had any issue with it but I'm still monitoring it.

Our current Joomla config

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

I dropped the shs404sef component, installed Speedcache from Joomunited and used the core SEF.  Site speed improved a lot, less crashes.

Update june 14th, 2018:  After trying JoomUnited's speedcache, Varnish, sh404sef, JCH Optimize... we came into a conclussion that LiteSpeed Cache is the BEST cache provider.  Of course that you need to be hosted on a server with LTS installed instead of Apache, Nginx, IIS.  We offer LTS to all our clients as well as LTS cache.

Comparission between Varnish and LTS?  Wow... Varnish is the closest contender to LTS but still a 2nd place with a huge gap in front of it.  Not only the configuration of the default.vcl is a pain in the butt, but the hated Guru errors that showed up to clients harming your ranking, traffic and reputation.

Litespeed cache is now available for Joomla!: First of all, make sure you have it on your hosting (hey, we offer it b default to all our clients!) and it's configuration is super fast.  We've been trying the ESI modules on some of our clients and on this page too and the loading time drops almost by half.

phpDesigner8 and UTF-8 accents

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive
This was a bad move.  I bought the phpDesigner8 attracted by price but didn't read it all because of the rush.  The software's last version was on 2013 although they still sell you licenses as if there were going to be updates.  I spent several hours dealing with broken UTF-8 until I found out the the Mysql collantion was fine, php charset was fine, everything was correct except... you guessed it: phpDesigner8 which was set on ANSI.  Had to change all my files to UTF-8 and it worked

Joomunited SocialBacklinks is not synchronizing

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

I have to be honest. Joomunited develop really good components and modules. I've suscribed to several of their products for more than 3 years but... their tech support lacks a little.

Well.  My SocialBacklinks stopped working but I had the same configuration on several websites. I tried disabling cache, minifiers, etc.  In the end, after several days, the criminal plugin was ShLib from sh404sef.  I had to uninstall sh404sef completely and it started working again.

Wordpress white screen of death

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

I never work with Wordpress but not because I don't like it, but because I know Joomla back and forth and I develop faster here.

I got a message from a friend who couldn't access the wp-admin site, it was a blank screen.  I went to SSH and ran lynx and curl to get the index.php of the wp-admin folder and I was getting redirected from a www domain to a non-www domain.  So far it looked like DNS, but it wasn't.

We disabled plugins and verified code. It wasn't the way.

After several hours, I took out the site url value of the table 'options' and ran the wp-admin to get an error about database connection with a 500 error code.  Then I added the line define('WP_ALLOW_REPAIR', true); to wp-config.php and it prompted me for an autorepair feature that wordpress has and returned the "site url" value to the 'options' table and it worked.  4 paragraphs that took 16 hours (that happens when you don't know what you are doing hahaha)
