Fresh install produces a blank page

Greetings Wackos

I have just finished installing/setting up Wacko 6.0.15 on a XAMPP x64 7.4.13-0-VC15 (XAMPP 8.0.0-2-VS16 does not support IPS

I did have to change the "const CACHE_SESSION_DIR" setting in config/constants.php. After that all of the things were checked off.

It said everything was installed correctly, but when I clicked on "take me to the wiki" it gave me a blank page.

Following the advice in this thread I enabled error reporting. I then hit ctrl+F5 on my wiki url and got this error
(formatted to be easier to read)

Fatal error: Uncaught Error: Class 'Normalizer' not found in F:\ff\htdocs\wiki\class\ut.php:586 Stack trace:
#0 F:\ff\htdocs\wiki\class\wacko.php(6807): Ut::normalize('ForgottenFreedo...')
#1 F:\ff\htdocs\wiki\index.php(62): Wacko->run('ForgottenFreedo...', 'show')
#2 {main} thrown in F:\ff\htdocs\wiki\class\ut.php on line 586	

Line 6807 of class/wacko.php is

 $tag = Ut::normalize($tag);	

Line 62 of index.php is

 $engine->run($route['page'], $route['method']);	

Line 586 of ut.php is

 static function normalize($string, $form = Normalizer::FORM_C)	

Even if my PHP was not rusty, I still would not know where to begin to try and fix my issue.

System specs:

  • Windows 10
  • XAMPP 7.4.13
    • Includes: Apache 2.4.46
    • MariaDB 10.4.17

    • Tomcat 7.0.107 (with mod_proxy_ajp as connector)
    • Strawberry Perl Portable

If there is any other information you need just let me know, and I will respond as soon as I can.

Thank you in advance.

    It seems that the intl extension is missing.
    Fatal error: Uncaught Error: Class 'Normalizer' not found	

    WackoWiki installation step 2: system requirements

    I tested only XAMPP for Linux, so I guessing that the intl extension is not enabled by default in XAMPP for Windows.

    I found two possible issues:
    1. How can I enable PHP extension intl in XAMPP for Windows?
      • Stop XAMPP and remove the starting semicolon ( ; ) from your xampp/php/php.ini the following code.
        Restart XAMPP.
    2. XAMPP Intl extension on Windows 10 can't be installed
      • XAMPP setup filename is contain VCXX for example xampp-windows-x64-7.4.13-0-VC15-installer.exe, VC15 mean that PHP compiled with Visual Studio 2017, so you need to install Microsoft Visual C++ Redistributable for Visual Studio 2017 to make PHP and Extensions running smoothly.

    Please check and ensure that the intl extension is enabled and installed correctly.

    I had a detailed reply, but when I hit "post" it said
    Session terminated due to timeout.
    Welcome back, Breantique
    so my detailed reply is lost to the inervoid.

    I followed the direction on that link, but then MySQL stopped connecting. Without MySQL I can't test to see if the wiki is fixed.
    Reverting the file change did not fix it.

    I'm looking in to how to fix that now.

    Besides the Feedback plugin being disabled I can't see any other issues. From what I have been reading that is supposed to be an optional thing. Correct me if I'm wrong.

    I fixed it.
    Somehow - I don't know how -
    had been un-commented.
    I don't remember making those changes this morning, but here we are.

    Also, I forgive you for making the defer change. If it makes your site more secure I am sure we can all learn to live with it. :P

  4. Re: Fresh install produces a blank page

    I am not sure how those two settings got changed in the first place. I disabled them both and MySQL connected again in the XAMPP cp.

    The next issue was that the user account I had created in the database "ff_admin" disappeared and all the tables for Wacko are empty or "don't exist"
      #1932 - Table 'ff_wiki.wiki_acl' doesn't exist in engine	

    Because the tables are empty I get
     Error loading WackoWiki config data: database `config` table is empty.	
    when I go to localhost/wiki

    Going to try a reinstall...
  5. Re: Fresh install produces a blank page

    I could not figure out why the database was freaking out.

    Since this is on my local machine, and I am the only one that uses my computer I didn't feel it necessary to remove the write privileges to the Wacko folders.

    This install was successful. I now see the WackoWiki front page on my localhost domain

    Next step is to reinstall IPS. Wish me luck, I hope it doesn't break anything now.
