Hello Everybody, I am experiencing a couple of problems with Wibbit, which may or may not be related to each other. First, to dispense with some details:
1. Apache 1.3.29 (& with mod_security 1.9.3, very lightly configured to catch XSS stuff, etc.; pretty relaxed rules. Also not seeing anything in modsec logs that would indicate it's interfering with the wiki+wibbit). 2. PHP 5.2.6 (with Suhosin patch & extension), running as an Apache .so extension 3. PECL's Advanced PHP Cache (APC) 3.0.19 4. MySQL 5.0.51 5. Mediawiki 1.13.3 set to use object caching of APC with $wgMainCacheType = CACHE_ACCEL; Now for the problems: 1. Using Seamonkey 1.1.14 browser, I go to my test page at http://redhelp.info/wiki/index.php/Wibbittest1 . I am using the data & wibbit markup from http://simile.mit.edu/axo/People . It works. 1A. However, if I edit the page, even making no changes, simply enter the edit page then save, the Exhibit display no longer works. I get the unadorned table instead. 1B. If I clear the Mediawiki cache, either by clearing the PHP user cache from the APC control panel, or by saving & thereby incrementing the 'last modified' stamp on Mediawiki's LocalSettings.php file (which expires the cache too), I get the Exhibit effect again. 1C. If I disable APC, % configure Mediawiki with $wgMainCacheType = CACHE_NONE;, then try to edit, I get the same problem. I must expire the Mediawiki cache by incrementing the time stamp on the LocalSetings.php file to get Wibbit functionality working again. 1D. With APC on & $wgMainCacheType = CACHE_NONE;, the problem persists. I check the APC control panel for user cache, but since Mediawiki is sett not to use the object cache, nothing appears there. Yet still Wibbit functionality fails after an edit, & will only return after chaging time stamp on LocalSettings.php. 1E. Same problem using the simple example found at http://simile.mit.edu/wiki/Wibbit/Walkthrough . 1F. Browser cache appears to have no bearing on this. So, any ideas what might be going on? What is Mediawiki storing away that is preventing Wibbit from loading Exhibit functionality after an edit, & can only be rectified by reloading the settings file? ------- The second problem: 2. This problem does not occur with Mozilla-based browsers, but does with Internet Explorer versions 6 & 7. (I haven't tested any others.) 2A. With IE, I browse to my test page at http://redhelp.info/wiki/index.php/Wibbittest1 . A pop-up displays the following error message: 'Caught exception: undefined. Details: Object doesn't support this property or method'. Furthermore, the Exhibit functionality doesn't work. Strangely enough, it doesn't entirely fail. I get the 'Class Year' entry box from the Exhibit demo, followed by the unadorned wiki table. 2B. I found that this error & failure also occurs on the SIMILE site as well: http://simile.mit.edu/axo/People . It doesn't, however, occur with the similar demo page at http://simile.mit.edu/axo/Disasters . (I did note that in IE6, the disaster icons in the key are stretched, but that's likely a different issue.) 2C. My server logs show the following error (not just when browsed with IE, but on all requests to my Wibbit test page): [error] PHP Notice: Trying to get property of non-object in /path/to/ extensions/exhibit/includes/Exhibit_Main.php on line 410'. Perhaps it's related? Anyway, what causes it? So, any ideas on this one would be appreciated as well. If any other information would be helpful, just ask.
