-===== A LiteMage ​troubleshooting case study ===== +====== A LiteMage ​Troubleshooting Showcase ======
-In this troubleshooting case study, we will show you multiple issues(including "​Loggin/​logout"​ issue, "​compare"​ issue and "​banner"​ disappears issue), troubleshooting processes and recommended solutions to fix them. We assume you might have been already familiar with Magento Layouts, blocks and templates and you know how to make proper change to them. You can read more from Magento 1.x Developer Reference located [[http://​devdocs.magento.com/​guides/​m1x/​magefordev/​mage-for-dev-4.html|here]].+
  
-==== Issue 1: Login/​Logout issue ==== +In this troubleshooting showcasewe will be looking ​at a case where a Magento site was having ​login/logout issuescomparison issuesand disappearing banner issues as well as the troubleshooting processes and recommended solutions to fix them
-At Home pagethere is one section ​at the top which says **"​Welcome Login or Create an Account"​**. With LiteMage enabled, If user is logged in, it shows "​Welcome Sam! Login or Create an Account"​ While it should show "​Welcome,​ Sam Logout!"​. Some time, LiteMage caches " Welcome, hole login or create account " if no one is logged in or it caches "​Welcomehole Logout"​ if a user is logged in. In that casefor other users which just opened ​the home page, it shows, "​Welcome,​ Logout"​.+
  
-The user uses theme SM Market. ​It looks like a template problem. Basically, we need to punch a hole for that piece of info together ​with the login buttonwith welcome tagPlease refer [[litespeed_wiki:cache:​litemage:​troubleshooting:​checking-hole-punching|this]] on how to check hole punching.+It is assumed ​that you are already familiar ​with Magento Layoutsblocks, and templates as well as how to make proper changes to themYou can find out more from the [[http://​devdocs.magento.com/​guides/​m1x/​magefordev/​mage-for-dev-4.html|Magento 1.x Developer Reference]].
  
-Global ​PHP variables ​can not be initialized in header.phtml and social.phtml, update those two files:+==== Issue 1: Login/​Logout ==== 
 + 
 +On the home page, there is a "​Welcome/​Login/​Create an Account"​ section at the top. If a user logs in, we expect to see something like ''​Welcome,​ Sam! Logout''​. With LiteMage installed, we were instead seeing ''​Welcome Sam! Login or Create an Account.''​ In this case, LiteMage cached ''​Welcome,​ <​punched_hole>​! Login or Create an Account''​ for a logged out user and served that to the logged in user. 
 + 
 +This issue was also happening in reverse! LiteMage would instead cache ''​Welcome,​ <​punched_hole>​! Logout''​ for a logged in user, serving ''​Welcome,​ ! Logout''​ to non-logged in users. 
 + 
 +Looking further, we see that the user uses the SM Market theme. It looks like a template problem. 
 + 
 +We need to punch a hole for that piece of info along with the login button and welcome tag. (**[[litespeed_wiki:​cache:​litemage:​troubleshooting:​checking-hole-punching|How to check hole punching]]**) 
 + 
 +Since LiteMage processes these ESI blocks in small chunks, some global ​PHP variables initialized in header.phtml and social.phtml ​were not available in these chunks. These two files needed to be updated to initialize them

 +==== Issue 2: Punching A Bigger Hole While Still Purging Private Sections ====
  
-==== Issue 2: Punch bigger ​hole and but still purge private sections ====+Now that the initialization problem is solved, we need to punch big hole instead of small one. Logging into the Magento Admin and entering LiteMage config, we add "​header"​ in **Customized Block Names for "​toplinks"​ Tag**. ​
  
-After initialization problem resolved, we need to punch big hole instead of small one. In MagentoAdmin LiteMage configenter "header" ​in Customized Block Names for "​toplinks" ​Tag+We also see "​compare"​ in toplinks blockso we add "compare" ​to **Additional Purge Tags for "​toplinks" ​Blocks** as well.
  
-We do see "​compare"​ on toplinks blocks, hence we need to put "​compare"​ in Additional Purge Tags for "​toplinks"​ Blocks. +{{ :​litespeed_wiki:​cache:​litemage:​troubleshooting:​litemage-see-minicompare-tag-add-purge.png?​nolink ​|}}

-==== Issue 3: banner disappear issue ==== +
-The above solutions fixed Loggin/​logout user showing wrong info issue. But due to the changes, the banner disappears from homepage.+
  
-After further investigation,​ we found out the header template includes logic to check if it's frontend or not. If it is frontend, then it show banner. So we cannot simply punch a big hole for the header. 
  
-The solution is go back to fix the login links. We basically needs to single out the logic and put it in its own block so we can hole punch it as a private block. ​The rest can be publicly cached.+==== Issue 3: The Case of The Disappearing Banner ====
  
-Copy original files as .bak.+At this point we have fixed the login/​logout issueGreat! Except now the banner has disappeared from the homepage.
  
-Header style selection ​is “header4”+After some further investigation,​ we found that the header template included logic to check if it is displaying on a frontend page or not. If it is not a frontend page, then the banner will not display. This stops us from simply punching a big hole for the header, like we did earlier.
  
-Inside ​[app/​design/​frontend/​sm_market/​default/​template/​page/​html]vi header4.phtml, We can see the logged-in link is mixed in the header template. ​We need to take that logic out and put in its own block and templateso we can punch a hole for that block.+We now needed to go back and "​fix"​ the login links. 
 + 
 +After making a copy of ''​header4.phtml'',​ the header style file, we open it to begin modifying.  
 + 
 +<​code>​ 
 +[app/​design/​frontend/​sm_market/​default/​template/​page/​html]vi header4.phtml 
 +</​code>​ 
 + 
 +Inside we can see the "​log ​in" ​link mixed into the header template. ​That logic needs to be taken out and put in its own block/template so we can both hole punch it as private ​block AND keep the rest of the header publicly cached.
