The “Posts By Date Range” plugin makes post filterable by date. No boundary to filter post by month, you can search posts for any date or date range. It can filter any type of post/page/custom post type and then builds the necessary interface using WordPress core functions to properly utilize it.

• Filter posts can be done via pre-defined and jQuery based drop down options. Such as -
  • Today
  • Last 7 Days
  • Month to date
  • Year to date
  • The previous Month
  • Specific Date
  • All Dates Before
  • All Dates After
  • Date Range
• One Click Install and Unistall option
• Minimum foot prints and resource utilization
• No design hack is needed
• No programming hack is needed
• Zero (0) Configuration and extremely simple to use!
• Built for WordPress 3.0+, other old version may work but not tested

Simple and Easy – Out of the Box:

Problem: Countless folks get this error while they attempt to install Joomla! content management system – “Error: the XML response that was returned from the server is invalid”

Solution # 1:

1. Open php.ini file
2. find this option setting –

   error_reporting = E_ALL

3. change the above setting to –

   error_reporting = E_ALL & ~E_NOTICE

Solution # 2:

1. Install Joomla without installing sample data.
2. Do not delete the Installation folder after installation is done.
3. Download the joomla.sql file from installation/sql/mysql or check joomla sample data folder - (…/yourjoomla/installation/sql/mysql/sample_data.sql)
4. Use PHPmyAdmin to install this SQL file into your Database.
5. If problem persist and Joomla installation force you to install sample data then edit sample_data.sql file and find

   TYPE=MyISAM

   and change to

   ENGINE=MyISAM

6. If you have created or copied a configuration.php file from configuration.php file-dist due to warning message in beginning of installation page. Just remove ‘configuration.php’ file, and just ignore the warning message. Now you won’t see the ‘Error:the xml response that was returned from the server is invalid’ again.

Solution # 3:

1. Check your PHP version. Joomla 1.5.x doesn’t support PHP 4.3.9, 4.4.2 or 5.0.4
2. Check your PHP version. Joomla 2.5.x, 1.7.x and 1.6.x requires PHP 5.2.4 +, PHP 5.3 + recommended
3. Joomla is not yet compatible with MySQL 6.x, check your mysql version

Still it is not working?

Solution # 4:

1. From php.ini file, check that extensions are enabled
2. In order to use SEO URLs, you will need to have the Apache mod_rewrite extension installed.
3. Check your PHP setting from php.ini file, you can check memory limit setting for sure. Edit the php.ini file of your system and set the “memory_limit” to at least 256M or 512M. For shared hosting, you may need to contact your hosting provider to change this setting.
4. Some systems have specific file permissions that might prevent a file from being readable. Find out the proper permissions for your hosting environment and apply them to the “…/yourjoomla/installation/sql/mysql/sample_data.sql” file or check Solution #2
5. Make sure the database user has all permissions on the database used

Email Address Checker

We need to validate email address by sending an email to visitor’s mailbox with unique verification code / activation code. Sometimes we need to check email address on the fly, where no time is available to send confirmation message to visitor’s mailbox. In this case, we cannot handle mail spammers or wrong email addresses.

We can resolve this issue with our email address checker tool. Which will ping any mailbox such as google mail, yahoo mail, other pop mail server / imap mail server etc. It has limitation for some Mail Exchange server such as AOL, ComCast etc. Most server response ping except a very few of them. This application checks email via Telnet.

If there is CATCH-ALL email feature enabled, this tool can not tell you specifically that mailbox exists or not. Though catch-all feature respond pings for any name / user.

But it is most comprehensive tool to verify visitor mailbox on the fly, at least you can say 90% to 95% email address are valid or invalid without sending mail.

You can use this tool in the feedback / enquire / contacts pages where we do not verify emails in most cases. If you get lots of query per day, then you can set priority of feedback of visitors upon the email status.

You can check email address from our “real time email verification tool – email address checker“. If you think you need this development, you can contact us. We will deploy this tool to your current forms or in new forms.
