What I love about working with the guys at Joomla Center, besides their excellent knowledge of their craft, is their patience and politeness. No irritation at stupid questions, no arrogance, no eye-rolling, no heavy sighs. On the contrary, they explain things very politely and clearly, give recommendations, do things quickly and competently, and if something goes wrong, they'll fix it just as quickly. Five stars on all counts! As they say now, I'm hooked!

I want to express my sincere gratitude to the Joomla Center team for their professional assistance! After my site was hacked, their specialists quickly identified and eliminated all the consequences of the attack, patched vulnerabilities, updated the software, and restored the site to its original state. I was especially pleased that the work was not only done efficiently but also with detailed explanations of all the steps taken.

Thanks to Anton and the Joomla Training Center for their excellent work. They upgraded my sites from the old Joomla to the new one. Everything works perfectly, even better than before. They professionally fixed numerous errors. I can only recommend them. They offer truly excellent quality and speed at relatively low prices.
